mount bug

[Sami Nieminen]

I am getting a random kernel bug upon mounting my SCSI dvd drive. It's
random because it doesn't happend every time when I mount. I copied some CDs
to SCSI hd during the past few days and had to mount/umount several times. 
Mount hung twice and I got the following message on my syslog:

This is SMP box (2xP3-850) with Abit VP6 motherboard (VIA), Tekram DC390 U2W 
SCSI controller and 512MB of RAM. It is running Mandrake kernel 2.4.7-6mdksmp, 
which is essentially a 2.4.7-ac5.

P.S. CC to me as I am not subscribed to lkml.
