Most recent kernel where this bug did not occur: 2.6.14-r5 Distribution: Gentoo Hardware Environment: ASUS A8N-SLI Motherboard, AMD64 3200 processor Software Environment: GCC 3.4.4 ... what else do you need? *stumped* Problem Description: I've been attempting to figure out this problem for a long time, and have come to the conclusion that it must be a kernel bug (that or perhaps I'm a bit dense). Whenever I have the option, "Device Drivers > Plug and Play > ACPI Support" enabled, I become unable to print using my parallel port. I'm using an ASUS A8N-SLI motherboard with an AMD64 3200 chip and 1GB of RAM. I have two printers, and this happens with both. Here are some forums in which I have tried to solve this problem: http://forums.gentoo.org/viewtopic-t-416986-highlight-.html http://www.linuxquestions.org/questions/showthread.php?t=380023 Steps to reproduce: Select the "Device Drivers > Plug and Play Support > Plug and Play ACPI Support" option in the kernel, recompile, reboot.

A few questions: Does your parallel port work if you disable PnP ACPI and enable PnPBIOS? I noticed PnPACPI doesn't appear to be enabled in the first dmesg posted, was this an example of the parport working correctly?

Yes, that is correct; sorry I didn't make that more clear. The first post is the 2.6.14-gentoo-r5 kernel with ACPI disabled and parallel printing working. The second post is the 2.6.9-gentoo-r9 kernel with ACPI enabled and parallel printing working. The third post is the 2.6.14-gentoo-r5 kernel with ACPI enabled and parallel printing broken. > This might be a problem with the parport probe code rather than ACPI. Entirely possible.

In `make menuconfig' you can search for config items. Do "/pnpbios". It says: Symbol: PNPBIOS [=y] Prompt: Plug and Play BIOS support (EXPERIMENTAL) Defined at drivers/pnp/pnpbios/Kconfig:4 Depends on: PNP && ISA && X86 && EXPERIMENTAL Location: -> Device Drivers -> Plug and Play support -> Plug and Play support (PNP [=y]) So it needs PNP && ISA && X86 && EXPERIMENTAL
I have PNP and Experimental selected, but for some reason I can't find anywhere to enable x86 or ISA. Perhaps this is because I'm using an AMD64 processor. I googled a bit for some more info and found this: Bus options (PCI, PCMCIA, EISA, MCA, ISA) * [*] PCI support * [*] ISA support (not needed anymore since 2.6.2-rc1) (http://secure.netroedge.com/~lm78/kernel26.html) Has ISA support been taken out of the kernel or disabled on x64 systems, or am I just not finding it? --Dane
Oh, you're using x86_64. arch/x86_64/Kconfig says: # Note: ISA is disabled and will hopefully never be enabled. # If you managed to buy an ISA x86-64 box you'll have to fix all the # ISA drivers you need yourself. As I say, the search command in `make menuconfig' is neat. On x86_64 it says: Symbol: PNPBIOS [=n] Prompt: Plug and Play BIOS support (EXPERIMENTAL) Defined at drivers/pnp/pnpbios/Kconfig:4 Depends on: PNP && ISA && X86 && EXPERIMENTAL Location: -> Device Drivers -> Plug and Play support So whoops, it doesn't seem possible to enable pnpbios on x86_64. Andi, is that sane?
yes. pnpbios is a 32bit BIOS service and can't be called from 64bit kernels. But newer ACPI has a special emulation where it tries to emulate pnpbios using ACPI motherboard resources description. That should work under 64bit in theory too. But I don't know details about that - the ACPI maintainers should know.
This bug persists in kernel 2.6.15-gentoo-r4. --Dane
This has been fixed in Ubuntu kernel 2.6.15-17-amd64-generic with ACPI loaded as modules. I'll take a crack at the latest Gentoo kernel and report my findings. --Dane
I was unable to compile ACPI support as modules, so I compiled them into the kernel. Now the printer lights flash a few times as normal, then stay lit and don't print anything. :-( --Dane
The bug is back in Ubuntu kernel 2.6.15-20-amd64-generic. Since I don't print much from ubuntu, the bug may also be there in the previous couple of releases as well.
Try boot param pnpacpi=off. Helps for me in apparently similar problem. (bugs.debian.org bug #406056) Anyway, this is a temp-hack, not a SOLUTION
On the latest kernel (2.6.20-rc6-g5263bf65), with Fedora Core 3 distribution, the bug is also there when using lp0 to debug ARM board through JTAG. When disable the CONFIG_PNPACPI, everything works well just like on kernel 2.6.9. I would like to dig this problem more since it blocks my work now ... :)
This looks similar to http://bugzilla.kernel.org/show_bug.cgi?id=7492 > (#10): This has been fixed in Ubuntu kernel 2.6.15-17-amd64-generic ... > (#12): The bug is back in Ubuntu kernel 2.6.15-20-amd64-generic. Can someone verify that the problem really went away in Ubuntu 2.6.15-17-amd64 and, if so, attach the complete dmesg? I suspect the problem is related to either the IRQ or the DMA channel reported by ACPI. The working dmesg logs show no IRQ (polling mode) and no DMA, while the non-working log shows interrupt mode and DMA channel 3. I'll attach patches to disable the PNP IRQ info and the PNP DMA info. Please try both (separately) and see whether one makes the port work.
Created attachment 12190 [details] disable PNP IRQ info If this patch makes the port work, please attach the dmesg log. Please make sure you have these in your .config: CONFIG_PNP=y CONFIG_PNPACPI=y
Created attachment 12191 [details] disable PNP DMA info If this patch makes the port work, please attach the dmesg log.
Created attachment 12211 [details] dmesg log
I have tested the IRQ patch with kernels 2.6.20-gentoo-r7 and 2.6.20-gentoo-r8, and in both cases, applying the patch fixed the problem. I now have CONFIG_PNP=y and CONFIG_PNPACPI=y, and I am able to print just fine! Attached is the dmesg log.
Looks like I spoke too soon. When trying to print multiple pages, or multiple documents, I find that the printer will just "hang" until I "killall -KILL parallel" (as root), cancel all print jobs, recycle the printer, and then start the printer via cups. The good news: some preliminary testing with BOTH patches applied seems to have fixed it completely. I'll let you know later how further testing goes. Attached is a dmesg log.
Created attachment 12250 [details] dmesg with both patches applied
Thanks for trying those. But I'm afraid I wasted your time. This tells us what we already knew: the port works when we run it with interrupts and DMA disabled. The question for me is whether the problem is in PNPACPI (where I might be able to fix it) or in the parport driver (where I don't have any clue what to look for). PNPACPI tells us the device uses IRQ 7 and DMA channel 3. Without PNPACPI, the probe found IRQ 7 (but didn't use the IRQ) and didn't look for the DMA channel. So I think PNPACPI is probably telling us the right thing. You don't have Windows on this box also, do you? If we could tell that Windows uses IRQ 7 and DMA channel 3, I'd be even more confident that the PNPACPI info is correct. I suspect this is really a parport_pc driver problem. I don't have any good ideas about how to explore that.
Maybe dmitry can help or add someone who can? comment #22 summarizes the problem...
Thanks for your continued work on this bug. I have booted into my Windows XP SP2 installation, and I was unable to find anything in the device manager (using the "resources by connection" view) that used IRQ 7. I could not find the parallel port listed at all in that view (under IRQ). The ECP printer port was, indeed, using DMA 3. Perhaps of note (and perhaps not...), the ACPI controller was using IRQ 9 in both BIOS and in Win. XP. I hope this helps. Please let me know if you need any more information.
It looks like PNPACPI is getting the right information. I scrounged up a parallel printer and found that it does actually work with my laptop, where PNPACPI gives an IRQ and DMA channel, so parport_pc *can* use IRQ and DMA, at least sometimes. Here's your log (non-working case): pnp: match found with the PnP device '00:09' and the driver 'parport_pc' parport: PnPBIOS parport detected. parport0: PC-style at 0x378 (0x778), irq 7, dma 3 [PCSPP,TRISTATE,COMPAT,ECP,DMA] Does it make any difference if you try this: - unload parport-related modules (lp, parport, parport_pc, etc) # cd /sys/bus/pnp/devices/00:09/ # echo disable > resources # echo clear > resources # echo activate > resources - reload parport modules It's a long shot, but sometimes the BIOS doesn't actually configure the device until we call _SRS, which we don't do by default.
Created attachment 12396 [details] dump AML byte stream and ACPI resources Does the printer work with any kernel that has PNPACPI enabled? Apparently it worked in 2.6.14-r5, but I think PNPACPI was disabled there so we were just using the legacy probe. If it worked with PNPACPI once, we must have broken it. I just came across this patch: http://git.kernel.org/?p=linux/kernel/git/torvalds/linux-2.6.git;a=commitdiff;h=ccc4c7bbd6a2d47bf5899c2c8cf2e0d176a4dc0f I don't think it has anything to do with your problem (it only affects the pnpacpi_encode_dma path, which is used when we tell the BIOS to configure the device), but it does remind me that the BIOS tells us other DMA attributes besides the channel. I can't find any drivers that actually look at the other attributes, but maybe we'd learn something interesting by looking at the actual resources from the BIOS and the way PNPACPI interprets them. If you collect the dmesg output with this patch (pnpacpi-debug) applied, I'll decode the parport resources by hand and see what they look like.
Created attachment 12414 [details] Dmesg output after using the commands in comment #25. I tried using the commands from comment #25, but it didn't seem to fix anything. It did, however, create some seemingly interesting dmesg output (attached). I also tried using the patch from the next comment, but I was unable to make the patch command work. Below is the output of the command: [root@Orchestrator linux]# patch -p1 < pnpacpi-debug.diff patching file drivers/pnp/pnpacpi/core.c Hunk #1 FAILED at 205. 1 out of 1 hunk FAILED -- saving rejects to file drivers/pnp/pnpacpi/core.c.rej patching file drivers/pnp/pnpacpi/rsparser.c Hunk #1 succeeded at 189 with fuzz 2 (offset -53 lines). patching file drivers/acpi/resources/rscreate.c ...and here is the rejected piece: [root@Orchestrator linux]# cat drivers/pnp/pnpacpi/core.c.rej *************** *** 205,210 **** if (dev->active) { /* parse allocated resource */ status = pnpacpi_parse_allocated_resource(device->handle, &dev->res); if (ACPI_FAILURE(status) && (status != AE_NOT_FOUND)) { --- 205,211 ---- if (dev->active) { /* parse allocated resource */ + dev_err(&dev->dev, "(%s) get resources\n", acpi_device_hid(device)); status = pnpacpi_parse_allocated_resource(device->handle, &dev->res); if (ACPI_FAILURE(status) && (status != AE_NOT_FOUND)) { I was trying to patch kernel 2.6.20-gentoo-r8. Any ideas?
As for whether PNPACPI worked in one of the kernels, I'm no longer sure. It would seem that it was disabled after all in the kernels mentioned above; I looked at my kernel .config and was unable to find any reference to it being enabled in either kernels 2.6.9-r9 or 2.6.14-r5, although it's possible (as I haven't used those kernels in quite some time) that the last time I compiled them, they were without the option enabled, whereas it was enabled, and working at some point.
Is it possible the IRQ edge/level is wrong in the _CRS? We did find such buggy BIOS. please attach the acpidump output, so we can check it.
What should I type to get the desired output? Should I do this while running a working kernel, or one displaying the bug? (I've since changed to Ubuntu Gutsy, but I'm willing to compile the kernel source to continue work on this bug.) Thanks.
try pmtools at http://www.kernel.org/pub/linux/kernel/people/lenb/acpi/utils/. Better do this when the bug exists.
Attached is the output of acpidump. Oddly enough, after compiling the kernel (2.6.23-1) with pnpacpi=y, the bug is not being manifested; I'm not sure why. I have also attached my .config file for verification that I used the right options.

Created attachment 13469 [details] Debug patch - 2.6.24-rc2 (might have slight offsets, but should patch...) Could you try this debug patch, pls. I expect this is the same bug like: https://bugzilla.novell.com/show_bug.cgi?id=180390 There the DSDT has two devices matching for parport_pc(both accessing the same IO ports!). The one has DMA enabled (PNP0401), the other one not (PNP0400). I could imagine the status (whether device is present or not) is not checked and the first of the two devices is just used. This patch prints out (possibly a bit too much, pls attach dmesg...) status of ACPIPNP checked ACPI devices. It also provides a module parameter for parport_pc: probe_ecp=0 will only check for PNP0400 device and should work? probe_ecp=1 will check for both devices and should not work. probe_ecp=2 will check for PNP0401 device and could work. I assume ECP/EPP could be configured via BIOS and the _STA func of either of the two devices should return not present and must be ignored. Can you also try to rmmod parport_pc, load it with all three, above parameters and also provide each dmesg (just the additional info).
In a WinXP, device manager has an option for parport to disable interrupt, and this option is enabled by default, this suggests winxp doesn't use interrupt.
Could it be that PNPACPI does not check _STA when a device registers? This would explain everything...
I recompiled the kernel after applying the provided patch, but when I tried to modprobe the parport_pc module with the specified parameters (after first rmmod-ing it), I get this: dane@Orchestrator:~$ sudo modprobe parport_pc probe_ecp=0 FATAL: Error inserting parport_pc (/lib/modules/2.6.23.1-custom/kernel/drivers/parport/parport_pc.ko): Unknown symbol in module, or unknown parameter (see dmesg) Any ideas?
Reply-To: akpm@linux-foundation.org what was in dmesg?
[16418.046778] parport_pc: Unknown parameter `probe_ecp' [16453.967575] parport_pc: Unknown parameter `probe_ecp' [16457.777193] parport_pc: Unknown parameter `probe_ecp' This is after trying to modprobe with each of the above options. The rest of dmesg was there before the modprobe commands, so I'm not posting it (unless you want me to).
Sorry it is ecp_probe (modinfo should show you): ecp_probe= Another test revealed that it's probably not that easy -> the correct ACPI device seem to get used. You could also add: CONFIG_PNP_DEBUG=y and add a #define DEBUG 1 in drivers/parport/parport_pc.c between: #undef DEBUG and #ifdef DEBUG and a: #define DEBUG_PARPORT 1 in include/linux/parport_pc.h after: #include <asm/io.h> If you run this with PNPBIOS and PNPACPI, I think we should have a all debug info that could be "quickly" fetched for the parallel device. But this might also not bring us further... PNPACPI BIOS parts export different settings than PNPBIOS parts and I am pretty sure the parsing etc. is correct. Maybe this machine is only supported with PNPBIOS and PNPACPI simply returns copy and pasted, wrong ACPI code that never was tested (supported Windows OS did only use PNPBIOS code in old times?). In this case pnpacpi=off is the only workaround that makes sense, maybe a blacklist could be added to activate this on all machines, which BIOS is older than xy like we do with acpi in general?
Created attachment 13496 [details] Disable pnpacpi on BIOSes older than 2004 2004 is just random for now. If this could get a solution, as much as dmidecode info of affected machines should get collected and possibly set this to a lower value... What do you think?
In case it might be helpful, here are the results of the modprobe commands: ecp_probe=0 - prints fine ecp_probe=1 - does not print at all ecp_probe=2 - does not print at all Let me know if there's anything else I can help you with.
Re comment #43, this suggests Thomas's guess is right, but I'm really confused about this. pnpacpi should already check device's present bit. pnpacpi uses acpi_bus_get_device to get a device, if the device isn't present, the routine should fail. But anyway, can you try 'cat /sys/devices/pnp0/*/id', and attach the output? This should tell us which pnp devices are existed.
Here you go: dane@Orchestrator:~$ cat /sys/devices/pnp0/*/id PNP0a08 PNP0a03 PNP0c02 PNP0c02 PNP0200 PNP0b00 PNP0800 PNP0c04 PNP0700 PNP0501 PNP0401 PNP0f13 PNP0303 PNP030b PNPb006 PNPb02f PNP0c02 PNP0c01
I was wrong, it's not the status. I just tried on a machine with parallel port. Switching to EPP in BIOS shows a PNP0400 device switching to ECP shows a PNP0401 device in /sys/devices/pnp0/*/id How pnpacpi devices are registered is rather complicated :) I need to have a more detailed look somewhen, I think I at least half way got it now... I expect now, that the ACPI parallel port BIOS implementation is just a template used by vendors for a lot of machines without any testing. I could imagine vendors disabled (e.g. in this case DMA) on broken machines in PNPBIOS tables, but not in ACPI BIOS tables in order to make it work. Therefore IMO patch in comment #42 should be preferred (maybe this should be embedded into i386 define only, or does it make sense to disable pnpacpi on IA64 or x86_64?). Dane, could you also attach dmidecode output, pls.
Created attachment 13513 [details] Output of dmidecode
Is it possible parport driver can always not use DMA, considering Winxp not use DMA? Or can it detect if DMA is working, and disable it if not?
Yes, I expect (at least some) people do not see a pnp bug, but parport_pc driver problem. AFAIK there exist some strange workarounds like reloading the driver in SUSE or similar. The driver also seem to sometimes try to use dma == 7, which it makes up on its own (asking some superIO chip, don't know) and is obviously wrong. Using dma=none as default parameter should fix the parallel port for some more people... Also according to Tim Waugh who's address is stated in the driver nobody will (and probably should not take the risk of modify the resource guessing magic) look at the driver any more: ----------- Thomas, I'm afraid no-one maintains the parport stuff any more. Tim. ------------ IMO we should close this one (or is the policy to let such "sleeper" bugs open for reference?)
thomas, do you plan to push the patch in comments #42 upstream?
Blacklisting BIOSes older than 2004 to use pnpbios as default instead of pnpacpi? Not because of this one. If more machines pop up where this makes sense. I expect Bjorn knows more broken PNP machines and whether this could help. He should have a final word on this. For the parport_pc device/driver..., I expect the driver itself is rather broken (some reported dma channel 7 was used, there exist loading un- and reloading driver workarounds, the author answered: don't touch it it's ugly, old and unmaintained, etc.). IMO the blacklisting should better not be done because of this one. You might want to reopen and close it as won't fix, workaround available (boot or driver params) or similar...
Workaround patch available in comment#42.
Created attachment 16246 [details] test patch for ACPI CA problem Dane, I think this problem is likely a symptom of an ACPI CA bug that I outlined here: http://marc.info/?l=linux-acpi&m=121141248600755&w=2 The patch I'm attaching here is definitely not the final fix, but if you still have the machine, it would be very helpful to know whether this patch fixes the problem you're seeing.
Thanks for the patch, Bjorn. Sadly, I no longer have that motherboard; I upgraded (selling my old motherboard/CPU/RAM/video card) just last month; otherwise I would gladly try this new patch and report back. I took a brief look at your outline, and at least it looks like you've managed to fix (or point out) some other problems in the process. Thanks for all your work.
If #53 is correct, then this is the same problem as bugzilla 9487.
Created attachment 16261 [details] PNPACPI: use _CRS IRQ descriptor length for _SRS This patch should fix the bug. Dane or Zhang, would you mind re-opening this so we can resolve it properly?
Re-opened, per Bjorn's request.
A patch similar to the one in comment #56 is in 2.6.26-rc6. If anybody can test it and report the results, that would be great.
Bjorn, can we close this bug as the patch is already upstream?
This bug was fixed by this commit: http://git.kernel.org/?p=linux/kernel/git/torvalds/linux-2.6.git;a=commitdiff;h=36d872a370d3d10e5a7faa9dcacce744260fb13b which appeared in 2.6.26.
