Hi folks,
My Linux computer oopsed again on accessing the CD drive. This is not the
first time, though I can not reproduce it in a predictable way.
(bash-2.02.1) frodo@arda:~$ uname -a
Linux arda 2.0.36 #7 Wed Nov 11 21:46:31 CET 1998 i586 unknown
This is 2.0.36-pre19, to be exact. The CD drive is a Philips CDD3600
SCSI Rewriter, connected to a no-name Future Domain PCI SCSI card: dmesg says
scsi0 <fdomain>: BIOS version 3.4 at 0xc8000 using scsi id 7
scsi0 <fdomain>: TMC-36C70 (PCI bus) chip at 0xf800 irq 9
scsi0 : Future Domain TMC-16x0 SCSI driver, version 5.44
All SCSI stuff is present as modules (loaded by kerneld). The kernel is
compiled by gcc 2.7.2.3. It was not patched; no non-default modules
were loaded or had been loaded.
At the time of the Oops, I was opening a (non-suid, non-root) xdos (dosemu)
window. When I tried to access the CDRom, xdos crashed. When I next
reloaded xdos, the oops happened. xdos was unkillable afterwards.
This is the relevant part of dmesg at that time:
scsi0 <fdomain>: BIOS version 3.4 at 0xc8000 using scsi id 7
scsi0 <fdomain>: TMC-36C70 (PCI bus) chip at 0xf800 irq 9
scsi0 : Future Domain TMC-16x0 SCSI driver, version 5.44
scsi : 1 host.

If you need more information, please feel free to ask. I can also test
patches. I have had a similar Oops in 2.0.36pre15 - I can resend it if
people want to see it.
Keep up the good work,
