I am seeing a peculiar, possibly timing sensitive, crash that looks
like if is probably in either atapicam or scsi_cd. The system is
CURRENT as of yesterday morning.

The crash happens frequently when nautilus starts up. It does not
always crash, but does so fairly frequently and leaves my laptop
locked in X with no access to the console. If nautilus starts, the
system continues without problems until X is terminated and restarted.

I managed to get a panic printout by switching back to vty0 (console)
while the X startup was in progress and I am entering the panic by
hand. Slight chance of a typo, but I have checked it a couple of
times.

For some reason I can't explain, I didn't get a crash dump, but I
probably can get one after a future crash. The easy fix is to remove
the DVD/CD-RW drive. FWIW, the system is an IBM T30 and it happens
with either APM or ACPI. I am attaching the dmesg and the config
file. Hopefully the mailer won't strip them.
