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.
