VT8367 [KT266] and high IDE load crashes

VT8367 [KT266] and high IDE load crashes

[Henning Schroeder]

Hello,

I have an ASUS A7V266-E Mainboard (VT8367 [KT266] Chipset, with VIA
IDE and Promise 20265 IDE Controller on board) that keeps crashing
under high IDE load. Athlon XP2000+ cpu, 1.5GiB DDR-RAM.

At each IDE port (running UDMA100), a MAXTOR 6L020J1 (four in total) 
running as master is connected.

The system runs fine for days, until I start massaging (e.g. running mysql 
over a raid-0 array of the four drives) the IDE system.
Using just one channel works perfectly, but as soon as I use two or
more channels heavily at the same time, it doesn´t take long for the
system to go down.

For testing, linux is installed on hda, so hdc, hde & hdf are unused.
I issue

badblocks -b 4096 -c 50000 -p 5 -v /dev/hdc &
badblocks -b 4096 -c 50000 -p 5 -v /dev/hde &
badblocks -b 4096 -c 50000 -p 5 -v /dev/hdg &

for stress testing and see the following after seconds, minutes or
hours:

hdc: timeout waiting for DMA
ide_dmaproc: chipset supported ide_dma_timeout func only: 14
hdc: status error: status=0x59 { DriveReady SeekComplete DataRequest Error }
hdc: status error: error=0x84 { DriveStatusError BadCRC }
hdc: drive not ready for command
hdc: timeout waiting for DMA
ide_dmaproc: chipset supported ide_dma_timeout func only: 14
hdc: status error: status=0x59 { DriveReady SeekComplete DataRequest Error }
hdc: status error: error=0x84 { DriveStatusError BadCRC }
hdc: drive not ready for command
[...]

(different hd´s everytime). After a while, the system either crashes
or says "Unable to handle kernel paging request..." and crashes with
blinking keyboard led´s (CapsLock/ScrollLock)

Sometimes, there is "timeout waiting for DMA" or "drive not ready for
command" interspersed.

When I reboot I usually find out that the root fs on hda4(!) is fried
(Kernel panic: VFS: Unable to mount root fs on 03:04). e2fsck finds
gazillions of errors, what I don´t quite understand, since hda
shouldn´t have been touched very much.

Switching to PIO helps, but is not an option (system is supposed to be a
fast budget MySQL-Server with RAID-0). Removing Hard Disks does
not help, the problem occurs as well when I use only drives at the VIA
interface or only ones on the Promise interface.

I tried kernels 2.2.20, 2.4.18, 2.4.17 with Andre Hedricks
ide.2.4.17.02152002.patch, 2.4.19p7, 2.4.19p7-ac2 and 2.4.19p7 with
Andre Hedricks ide-2.4.19-p7.all.convert.6.patch. Same everywhere.

I tried BIOS versions 1004, 1007 and 1008.003 beta. No avail.

I changed and rerouted IDE cables. The PSU should be okay as well,
because it happens with only two drives (less load on the PSU) too. RAM is fine 
(several days of memtest86).

>From reading this list and googling it seems that problems like these
seem to be quite common, but i couldn´t find out whether they are likely
to be solved any time soon. Would I be better off just replacing the
board? From my understanding, the KT266 is the problem here, so would a
AMD761/VT82C686B chipset be trouble free?

Attached is some further information, I´d be happy to provide more 
if wanted/needed.

This is the same problem that I have attempted to report with regards to the 
Athlon processors. It's especially nasty when you mix scsi modules + the ide 
stuff. I hard compiled everything into the kernel before, but I still have 
problems.

Just now my computer crashed when I was attempting to mount my floppy drive. 
In fact, it crashes all the time (when in X) when I attempt to mount my floppy 
drive during or after high IDE activity.


See attached messages for more information.

Hi Andre, hi list!

I'm also having random lockups with an ASUS A7V266-E Mainboard, Athlon
XP 1800+.
Chipset is the VIA KT266A, kernel 2.4.18 (SuSE version 2.4.18-58, from
SuSE 8.0).
Nothing in the logs.

Andre, could you verify your possible answer? Any results?

Thanks, Richard

Hi Josh,

I think I have an answer why the crash but I need to verify with a client
as we are seeing the same problem on various VIA boards.  The good new is
we found on board that does not do this nasty.  So we are doing a
component wide comparisong of settings.

It is a really cool and smart embedded server found at

I think I tried the pentium stuff, but that would freeze up the computer 
too (the HD light comes on, and nothing else works, not even ping(!)) 
But I think that was for a <=2.4.14. I should try it again.

Here's the output of lspci:

New news, I got up this morning and the computer was frozen again. This 
time, I compiled in the kernel (not as modules) SCSI, SCSI CD, SCSI 
Disk, PPA, completely removed ide-scsi stuff, compiled in ide-cdrom. So 
I took ide-scsi out of the loop altogether.
