aec62xx: fix AEC6260[R] support on Macintosh (2.66 KB, patch) 2008-11-09 08:08 UTC, Bartlomiej Zolnierkiewicz	Details \| Diff
Add an attachment (proposed patch, testcase, etc.)

Description Eric Shaffer 2008-11-02 23:58:34 UTC

Latest working kernel version: none
Earliest failing kernel version: 2.6.24-19
Distribution: Ubuntu
Hardware Environment: PowerMac B&W G3(rev.1) upgraded to G4 600 mHz cpu, AEC6260 (ide-pci card)
Software Environment: Ubuntu Intrepid
Problem Description: Install successful from Live CD (Hardy) and Alternate CD (Hardy / Intrepid). Boot proceeds normally until:
scsi0:MESH 
hde: max request size: 128KiB
boot hangs with repeated lost interrupt, DMA recovery messages. Boot cannot proceed beyond this point. 
 

Steps to reproduce:

Comment 1 Andrew Morton 2008-11-03 00:27:57 UTC

Thanks - I'll reassign this to io-ide (although it sounds like an
acpi or x86 problem).

Comment 2 Bartlomiej Zolnierkiewicz 2008-11-03 04:52:54 UTC

Could you try some newer kernel like 2.6.27 or 2.6.28-rc3?

Also did it work OK with some earlier kernel?

[ From the bugreport it seems that kernel from Live CD works OK? ]

Thanks.

Comment 3 Eric Shaffer 2008-11-03 10:03:26 UTC

I am happy to  attempt a newer kernel if I can. While technically minded, I am fairly new to Linux and can only load from Live CD or alt CD. Research to date hasn't shown updating kernel from CD as possible...?

Hardy (2.6.24-19) failed at the same point in the boot process as Intrepid. No other kernel attempted to date. 

The Hardy Live CD worked flawlessly, even wireless connection, which is why I installed. I presumed if the Live CD worked it meant an install would also.

Comment 4 Eric Shaffer 2008-11-03 10:16:19 UTC

I have also tried startx from terminal at root (hde3) on rescue cd, Ibex loads but keyboard and mouse are unresponsive.

I have applied a firmware update to the AEC 6260M and the system will now recognize the partitions, cylinder, block data etc. Unfortunately the boot process still hangs at SCSI 0: with lost interrupts / DMA recovery messages.

Comment 7 Eric Shaffer 2008-11-07 19:13:48 UTC

I must use the irqpoll option for the partition check to be successful.

Comment 8 Bartlomiej Zolnierkiewicz 2008-11-09 08:07:46 UTC

It could be that AEC6260[R] controllers may need the same quirks (i.e. explicitly enabling IRQ line output) as AEC6280[R] ones on Macintosh (draft patch for 2.6.28-rc3 attached to the next comment).

When it comes to questions related to upating kernel in Ubuntu I think that it would be the best to try to get some help from Ubuntu Kernel Team  (added Ben to cc:) as I can't help much here.

Comment 10 Alan 2008-11-09 08:58:09 UTC

If the BIOS isn't getting run then that patch seems plausible IFF the registers are the same between the chips. I don't have enough Artop docs here to tell.

Probably worth getting an lspci -vvxxx from it (off a live cd or similar) to see what it look slike.

Can you redo that as the root user - only root can access registers > 0x3F which is what we need to see in this case.

Comment 14 Bartlomiej Zolnierkiewicz 2008-11-09 13:50:38 UTC

Thanks.  Could you try booting your installed system with "hde=nodma" kernel option, and if that works do (as root):

setpci -s 01:04.0 4a.b=86
hdparm -d1 /dev/hde

and see if hde continues to work fine (now with DMA mode enabled)?

Comment 15 Bartlomiej Zolnierkiewicz 2008-11-09 14:05:13 UTC

Update: hdparm -d1 /dev/hda won't work since we removed CONFIG_IDEDMA_PCI_AUTO config option before 2.6.24 but it still would be to useful to boot with "hde=nodma" and no "irqpoll".

Comment 16 Eric Shaffer 2008-11-09 14:26:12 UTC

hde=nodma - unsuccessful
hde=nodma hdf=nodma hdh=nodma - unsuccessful

Still experiencing boot stall at scsi0 : MESH

Sorry but have to ask, is there something I am meant to do with this patch or is this internal communication?

Comment 18 Bartlomiej Zolnierkiewicz 2008-11-09 15:00:01 UTC

Do SCSI and IDE devices share IRQs?  Could you post the output of 'cat /proc/interrupts' from the "irqpoll" kernel?

PS I don't think that there is a need to do anything with the patch currently.

Comment 19 Eric Shaffer 2008-11-09 15:20:05 UTC

Unfortunately I am uncertain how to get that output from the "irqpoll" kernel. I tried $cat /proc/interrupts and got this output (from Live CD no?) :

ubuntu@ubuntu:~$ cat /proc/interrupts
           CPU0

 42:         71   PMAC-PIC  Edge      BMAC-misc
BAD:          0

I also tried (beyond hope! :)) $cat /media/disk/proc/interrupts but receive an error message of cat: /media/disk/proc/interrupts: no such file or directory. Is it possible that since the "irqpoll" kernel has never completed booting this file has not yet been written? 

Someday I will know more than just enough to be a danger to my system...until then, I need a little more guidance on this one please.

Comment 20 Bartlomiej Zolnierkiewicz 2008-11-09 15:45:07 UTC

Ah, now I understand -- "irqpoll" only helps in getting past IDE messages but boot still hangs on mesh driver initialization, right? [ I thought that you can now boot successfully the installed system using "irqpoll". ]

If so this really looks more like a generic platform problem affecting both IDE and SCSI (mesh driver has an "interesting" IRQ handling routine that will loop forever if IRQ is not cleared).

If the mesh driver is compiled as module in Ubuntu (I don't know that) you may try blacklisting mesh driver (so it won't be run) by:

- booting from LiveCD

and

- editing /media/disk/etc/modprobe.d/blacklist file
  (just add "blacklist mesh" line at the end of it)

Correct, "irqpoll /irqfixup" only allow the system to read the partition and
disk info prior to scsi0 : MESH init. Still results in hang at scsi0 : MESH
with subsequent hde/f/h: lost interrupt messages. Installed system has never
successfully completed boot with or without "irqpoll / irqfixup". 

It is curious though that Live CD and alternate CD both load and operate
without error (no hang or stall)...this is dmesg snip from Live CD:

"blacklist mesh" has no apparent effect with or without "irqpoll/irqfixup" when added to /media/disk/etc/modprobe.d/blacklist.

Comment 24 Bartlomiej Zolnierkiewicz 2008-11-13 13:17:18 UTC

Thanks for testing it anyway.  It really seems like a platform specific issue so I'll re-assing this bug to Platform/PPC for now.

Comment 25 Eric Shaffer 2009-02-26 10:49:44 UTC

Any update on this issue?

Comment 26 Alan 2012-05-22 15:11:29 UTC

Closing as drivers/ide is now obsolete
