IDE Timeout problem on Intel PIIX3 (Triton 2) chipset

IDE Timeout problem on Intel PIIX3 (Triton 2) chipset

[Patrick Dreker]

Hello...

Any kernel above and including 2.4.21 (including 2.6.5 and 2.6.7, others not 
tested) produces the following errors quite often (once or twice per minute, 
with the corresponding delay) and the harddisk drops out of DMA.

-------------------------------------------------
hda: dma_timer_expiry: dma status == 0x20
hda: timeout waiting for DMA
hda: timeout waiting for DMA
hda: (__ide_dma_test_irq) called while not waiting
hda: status error: status=0x58 { DriveReady SeekComplete DataRequest }

hda: drive not ready for command
-----------------------------------------------

I have checked that the drive and cable are OK (tested in another machine) and 
no matter what drive I connect to the IDE controller, they *all* produce the 
above error and drop DMA after some seconds.

Currently I am stuck at kernel version 2.4.20, as any later kernel severely 
degrades the performance of the machine (Pentium Pro 200).

At http://www.uwsg.iu.edu/hypermail/linux/kernel/0304.1/0332.html I found a 
thread which hints that IRQ sharing maybe the culprit, but /proc/interrupts 
shows that the ide interrupt is not shared...

lspci and /proc/interrupts are included at the end of this mail.

What can I do to debug this problem?

Thanks,
Patrick

Same here. 3 computers with PIIX4, 2 (or maybe even 3, need to check the
850M Conner too) different disks (all pre-udma but mwdma, 2.5G Seagate
Medalist and 850M WD Caviar). The common denominator seems to be PIIX
chip (PIIX3 and PIIX4 reported so far) and multiword DMA.

It came with 2.4.19 for me - 2.4.18 (and thus also Debian Woody) is fine
but anything with a newer kernel (incl. 2.6.*) is broken - DMA timeouts.

So maybe it is a little different (since your 2.4.20 works) but still
very similar.

This was HPT specific problem.

"diff -u" on "lspci -s 07.1 -xxx" outputs for 2.4.20 and 2.4.21 kernels.

Doing bisection search on 2.4.21-pre kernels would also help.

Linux 2.4.26-UP is fine for me here, for both hda and
hdb. This box has 64 MB RAM, amd the kernel is
compiled with gcc-3.2.3.

I will do the bisection search first and then post the lspci diff between the 
last working revision and the first non-working version as I have to 
recompile everything anyways.

Thanks,

Actually I tested 2.4.19, 20, 21, 22, 24, 26 and 2.6.5 and 7 and all from 
2.4.21 on fail. All kernels compiled for SMP, but the system only has one CPU 
(second CPU is waiting for the IDE problem to tracked down...)

I have triggered a compile of all pre and rc version between 2.4.20 and 2.4.21 
and will do narrow it down tomorrow. (I know I'll probably need only 3 or 4 
of those kernels, but having them all available will make testing easier...

2.4.21-pre1 is the first non-working kernel, 2.4.20 works. When generating the 
configs for 2.4.21-pre1 (make oldconfig based on the working 2.4.20 config) I 
was asked "Use IDE Taskfile I/O" which defaulted to no and I kept that 
default (i.e. "Don't use Taskfile I/O").

lspci -s 07.1 -xxx shows no difference between a working (2.4.20) kernel and a 
non-working (2.4.21-pre1) kernel.

This caught my eye, but was probably obvious to you:
2.4.21-pre1 reports IDE Version 7.00beta-2.4 while 2.4.20 reports version 6.31
