[2.6.0-mm1] kernel BUG in include/linux/list.h:148!

[Joshua Kwan]

Got one of these while messing with some DVDs and CDs (mounting them,
etc.) One of them was not inside the drive correctly, so i had to eject
it while mount was running. Could this have happened then? I didn't look
at dmesg immediately after when that may have occurred.
