Oops didn't make it to the logs, I copied it by hand. Disks were dead at
that point, ALT+SysRQ+S didn't work.

ksymoops says:

I just tried to 'modprobe ide-cd' without the 'mount' and got:

System is still usable this time though.

Module Size Used by
ide-cd 20496 2 (uninitialized)

Anything else that may be of help? (Like ide-cd as not a module?)
