Some more information; I put in a Zod DVD to do an upgrade and the BIOS wasn't
set to boot from CD. So when I came back to the computer I had the usual
lockup, but this time a stacktrace as well! Included for your debugging pleasure:
BUG: spinlock recursion on CPU#0, swapper/0 (Not tainted)
lock: c06e6980, .magic: dead4end, .owner: swapper/0, .owner_cpu: 0
[<f8930c9e>] cdrom_decode_status+0x219/0x2a5 [ide_cd]
[<f8931466>] cdrom_read_intr+0x58/0x30e [ide_cd]
Hopefully I typed all that correctly...

For grins I replaced the Pioneer writer with an LG writer and the kernel crash
gives the same stack.
Someone with perms can set this for fc6, and clear NEEDINFO unless there's more
