------- Comment #2 from [email protected] 2008-11-03 04:52 ------- 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 from [email protected] 2008-11-03 10:03 ------- 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.

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 #8 from [email protected] 2008-11-09 08:07 ------- 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 from [email protected] 2008-11-09 08:58 ------- 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.

------- Comment #14 from [email protected] 2008-11-09 13:50 ------- 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)?

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".

aec62xx: fix AEC6260[R] support on Macintosh

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

------- Comment #18 from [email protected] 2008-11-09 15:00 ------- 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 from [email protected] 2008-11-09 15:20 ------- 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 from [email protected] 2008-11-09 15:45 ------- 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).

------- Comment #21 from [email protected] 2008-11-09 15:52 ------- 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:

------- Comment #23 from [email protected] 2008-11-09 16:42 ------- "blacklist mesh" has no apparent effect with or without "irqpoll/irqfixup" when added to /media/disk/etc/modprobe.d/blacklist.

------- Comment #24 from [email protected] 2008-11-13 13:17 ------- 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.
