That darn IDE CDROM problem...

I (finally) managed to hang a shell script that mounts a CD, although I
could switch to another VC and get info from there. I ran the script,
did some stuff with directores, but not involving the CD, ran the script
again and it hung.

dmesg:
hdb: ATAPI 4X CDROM drive, 128kB Cache
Uniform CDROM driver Revision: 2.13
VFS: Disk change detected on device 03:40
hdb: irq timeout: status=0xd0 { Busy }
hdb: ATAPI reset complete
ATAPI device hdb:
Error: Unit attention -- (Sense key=0x06)
Power on, reset or bus device reset occurred -- (asc=0x29, ascq=0x00)
ATAPI device hdb:
Error: Unit attention -- (Sense key=0x06)
Not ready to ready transition, medium may have changed -- (asc=0x28,
ascq=0x00)
VFS: Disk change detected on device 03:40

The first two lines are from the first mount of the CD -- I use kmod.

Syslog says nothing. Checking top, mount (version 2.71) has a status of
"uninterruptable sleep", which apparently means I can't kill it. This
is probably not reproducable, but I will try anyway.
