whenever trying to mount my cdrom with the command
mount /dev/cdrom /mnt -t iso9660
i recieve an oops from the kernel
this only happens the first time i try to mount it
the second time my computer locks hard
my computer is a dual celeron366 on an abit bp6 motherboard
i have a 13g ibm hard drive and cdrom reported as
hdb: WPI CDS-24X, ATAPI CDROM drive
both drives are on the bp6's standard ide controller and i have no devices
on the hpt366 controller
