One idea would be to inject more faults into disk (ATA)
as opposed to the Optical (ATAPI) drives, and see if doing
so in combination with the existing ATAPI poll/fails will
trigger things more quickly.

This can be done by using Passthru to issue invalid commands
to a drive, which the drive will reject with "Drive Status Errors".

I just tried it now on a whim, using "hdparm -Z /dev/sda",
and my system never recovered until I used ctrl-alt-sysreq-b.

Now mind you, "hdparm -Z" sends a Seagate vendor-unique opcode
(to my Fujitsu hard drive), and perhaps that maps to something
the Fujitsu recognized or choked on..  But one could edit
hdparm to send a NOP or something instead.

Cheers
