(With previous kernels, 2.6.12.6 and older, no such problems). I tried these configuration changes with 2.6.13, but no improvement: CONFIG_PREEMPT=y and CONFIG_PREEMPT_VOLUNTARY=y CONFIG_DEBUG_INFO=y and CONFIG_DEBUG_INFO is not set CONFIG_PCI_MSI=y and CONFIG_PCI_MSI is not set CONFIG_HWMON=m and CONFIG_HWMON is not set CONFIG_INOTIFY=y and CONFIG_INOTIFY is not set Also these commandline parameters didn't help: pci=usepirqmask (empty) noapic nolapic apm=off noacpi pci=noacpi,usepirqmask These parts worked correctly: USB subsystem (mouse, USB stick) X windows & gmplayer & AGP graphic card

2.6.13-git9-x03 kernel has the very similar problems on my hardware - I don't hear sound card while playing mp3 - after connecting network cable to b44 network card system is frozen PCI assignement and outputs of lspci are exactly the same like 2.6.13.1 Maybe these differencies of /proc will be useful for you too (the same with diff 2.6.12.6 and 2.6.13.1): diff -urU5 2.6.12.6-x02/proc/iomem 2.6.13-git9-x03/proc/iomem --- 2.6.12.6-x02/proc/iomem 2005-09-13 00:56:35.611577384 +0200 +++ 2.6.13-git9-x03/proc/iomem 2005-09-13 07:31:54.306981080 +0200 @@ -2,20 +2,23 @@ 0009fc00-0009ffff : reserved 000a0000-000bffff : Video RAM area 000c0000-000cebff : Video ROM 000f0000-000fffff : System ROM 00100000-1fffbfff : System RAM - 00100000-002e7173 : Kernel code - 002e7174-003946ff : Kernel data + 00100000-002dc2f9 : Kernel code + 002dc2fa-00352ea7 : Kernel data 1fffc000-1fffefff : ACPI Tables 1ffff000-1fffffff : ACPI Non-volatile Storage +20000000-20003fff : 0000:00:0a.0 f1000000-f10000ff : 0000:00:10.3 f1800000-f1801fff : 0000:00:09.0 f1800000-f1801fff : b44 f2000000-f3dfffff : PCI Bus #01 f2000000-f2ffffff : 0000:01:00.0 +f3ef0000-f3ef3fff : 0000:00:09.0 f3f00000-f7ffffff : PCI Bus #01 + f3fe0000-f3ffffff : 0000:01:00.0 f4000000-f7ffffff : 0000:01:00.0 f8000000-fbffffff : 0000:00:00.0 fec00000-fec00fff : reserved fee00000-fee00fff : reserved ffff0000-ffffffff : reserved diff -urU5 2.6.12.6-x02/proc/ioports 2.6.13-git9-x03/proc/ioports --- 2.6.12.6-x02/proc/ioports 2005-09-13 00:56:35.611577384 +0200 +++ 2.6.13-git9-x03/proc/ioports 2005-09-13 07:31:54.306981080 +0200 @@ -26,5 +26,7 @@ d000-d01f : uhci_hcd d400-d47f : 0000:00:0d.0 d400-d47f : ALS4000 d800-d81f : 0000:00:0a.0 d800-d81f : ne2k-pci +e400-e47f : 0000:00:11.0 +e800-e80f : 0000:00:11.0

So we haven't fixed it yet. Linus, Ivan, could you please take a look at http://bugzilla.kernel.org/show_bug.cgi?id=5235 ? especially this: - I/O behind bridge: 0000e000-0000dfff + I/O behind bridge: 0000f000-00000fff a size of -1...

This is perfectly fine - there are no IO ports behind the AGP bridge (video card has only MMIO registers), so IO window gets disabled. I'd rather blame supposedly wrong IRQ assignment: -PCI: Enabling device 0000:00:0a.0 (0000 -> 0001) -PCI: Found IRQ 11 for device 0000:00:0a.0 -PCI: Sharing IRQ 11 with 0000:00:0d.0 -PCI: Sharing IRQ 11 with 0000:01:00.0 -eth1: RealTek RTL-8029 found at 0xd800, IRQ 11, 52:54:AB:4D:BC:C1. +PCI: Enabling device 0000:00:0a.0 (0000 -> 0003) +PCI: setting IRQ 9 as level-triggered +PCI: Assigned IRQ 9 for device 0000:00:0a.0 +PCI: Sharing IRQ 9 with 0000:00:0d.0 +eth1: RealTek RTL-8029 found at 0xd800, IRQ 9, 52:54:AB:4D:BC:C1.

Len, could you please take a look and if this is an APCI problem, set the bug ownership appropriately?

If yes, does booting with "acpi=noirq" or "pnpacpi=off" make the same difference? it would be ideal if you could attach the complete dmesg files rather than just the diff.
I was not able add atachements via "Create a New Attachment", so I put it to http://decef.elf.stuba.sk/~pg20207/bug_5235_2.6.13.tar.bz2 There are dmesgs, .configs, lspcis and /proc files from 2.6.12.6, 2.6.13.1 and 2.6.13-git9 I'll try "acpi=off" after 10 hours, currently I am only remotely connected to my machine.
> I'll try "acpi=off" after 10 hours But from the dmesg logs, it looks like CONFIG_ACPI isn't even turned on. I'm a dunce and haven't figured out a good way to browse per-file revision history. But if I *could* do that, I'd start looking at arch/i386/pci/irq.c.
> But from the dmesg logs, it looks like CONFIG_ACPI isn't even > turned on. Of course, I didn't realise this... I use only APM for powering down machine. I tried "acpi=off" and logicaly no real change in behaviour of kernel. I noticed another thing - when I leaved machine in frozen state (2.6.13-git9) cca 2 hours, then I rebooted machine and it was not able to boot - DISK FAILURE or such message. Then I switched off machine for some minutes and after that it continued working normally (2.6.12.6). I don't know whether this has some relation to kernel problem, but I don't remember disk failures in past. Some ideas how to narrow problem? Now I have some time to experiments.
> Some ideas how to narrow problem? Now I have some time to experiments. Somebody probably has better ideas, but since I don't know how non-ACPI IRQ routing works, my approach would be the brute-force one of sprinkling printks through pcibios_lookup_irq() and related things, and try to figure out what changed between 2.6.12.6 and 2.6.13. And maybe booting with "debug apic=debug" would cause more useful output.
How about enabling ACPI for your system? That might fix the routing issue...
> How about enabling ACPI for your system? That might fix the routing issue... This solved my problem, now network and sound cards work correctly on 2.6.13.1 Changes in .config: CONFIG_ACPI=y CONFIG_ACPI_DEBUG=y CONFIG_APM is not set CONFIG_PCI_DEBUG=y Kernel command line: pci=usepirqmask debug apic=debug Details: http://decef.elf.stuba.sk/~pg20207/bug_5235_with_acpi.tar.bz2
Great, I'll mark this as fixed now...

> Great, I'll mark this as fixed now... Well, but... it *used* to work without ACPI. And now it doesn't. Is that an acceptable regression? How do we recognize and deal with future, similar bug reports? I'd feel better if we understood exactly what changed in the non-ACPI case, and we made a conscious decision that it was unavoidable.<html><head><meta DEFANGED_name="qrichtext" content="1" /></head><body DEFANGED_style="font-size:12pt;font-family:Courier New"> <p>> Great, I'll mark this as fixed now...</p> <p></p> <p>Well, but... it *used* to work without ACPI.

Hopefully bugzilla won't crash this time :) After narrowing this bug in code it seems the problem is hardware specific. In nonACPI case, kernel 2.6.12-git5 was working correctly, but 2.6.12-git6 not. I find out the small diff, which brought problems: diff -Naurp linux-x03/arch/i386/pci/irq.c linux6/arch/i386/pci/irq.c --- linux-x03/arch/i386/pci/irq.c 2005-06-17 21:48:29.000000000 +0200 +++ linux6/arch/i386/pci/irq.c 2005-09-18 22:46:25.619910392 +0200 @@ -227,6 +227,24 @@ static int pirq_via_set(struct pci_dev * } /* + * The VIA pirq rules are nibble-based, like ALI, + * but without the ugly irq number munging. + * However, for 82C586, nibble map is different . + */ +static int pirq_via586_get(struct pci_dev *router, struct pci_dev *dev, int pirq) +{ + static unsigned int pirqmap[4] = { 3, 2, 5, 1 }; + return read_config_nybble(router, 0x55, pirqmap[pirq-1]); +} + +static int pirq_via586_set(struct pci_dev *router, struct pci_dev *dev, int pirq, int irq) +{ + static unsigned int pirqmap[4] = { 3, 2, 5, 1 }; + write_config_nybble(router, 0x55, pirqmap[pirq-1], irq); + return 1; +} + +/* * ITE 8330G pirq rules are nibble-based * FIXME: pirqmap may be { 1, 0, 3, 2 }, * 2+3 are both mapped to irq 9 on my system @@ -512,6 +530,10 @@ static __init int via_router_probe(struc switch(device) { case PCI_DEVICE_ID_VIA_82C586_0: + r->name = "VIA"; + r->get = pirq_via586_get; + r->set = pirq_via586_set; + return 1; case PCI_DEVICE_ID_VIA_82C596: case PCI_DEVICE_ID_VIA_82C686: case PCI_DEVICE_ID_VIA_8231: After this patch the common problems appeared - sound and network cards broken.

You might ping Aleksey_Gorelov@Phoenix.com, the patch is added by him from the log. He should know about your issue.
Similar problem has been reported before here: http://groups.google.com/group/linux.kernel/browse_thread/thread/def4ca19dbc3cd4/5cffbf349f2c87a4?tvc=2&q=Aleksey+Gorelov&hl=en#5cffbf349f2c87a4 and was related to bug in BIOS reporting 82C686 router compatible to 586. I suspect BIOS on this board has similar issue: reports VT8235 router to be compatible with 586 one - which is obviously not true. Patch from the link above has already incorporated in both 2.6 & 2.4 series, but might not work in this particular case.
