Subjectcrash: asus sp3, aha2940 + scd0
Date

this is a system crash that I could reproduce regardless of the kernel
version, 1.2.x crashes as well as 1.3.x as well as 1.99.x
actually it is not a crash, but corruption of ext2fs.

hardware:
- aha2940
- scsi cdrom (no other device on scsi bus)
- eide disk (quantum fireball)
- asus sp3 board (4PCI, 1VLB, 3ISA)
the chips are labelled:
SiS
85C496
9511 NV
(C)(M)SIS'94
PFD3030

and

SIS
85C497
9509 NV
(C)(M)SIS'94
PFD2830

how to crash:

dd if=/dev/scd0 of=/dev/null

then log in on a different VC, do some work.
log in on another console, do some work ...
ls -laR / might help to make the bug come up more quickly.

soon you'll get
{ hda irq timeout }
{ Seek Complete Error }

resetting ide0

etc...

which occassionally will lead to a FS corruption.

I'll changed the board now (GA5486AL) with ALI chipset (4PCI, 4ISA)
and the problem went away. however, I'm still able to crash the machine,
but now less frequently and in a different way. I'll probably report
later.
