I've finally managed to get this to compile and test. (Hit a bug with
Debian's make-kpkg and other nuisances...)

The problem is still there. On some resumes I get the dreadful dead
disk again:

end_request: I/O error , dev sda sector ...
sd 0:0:0:0: [sda] Unhandled error code
sd 0:0:0:0: [sda] Result: hostbyte=DID_BAD_TARGET driverbyte=DRIVER_OK
sd 0:0:0:0: [sda] CDB: Read(10): 28 00 0e a4 77 a8 0 00 08 00
(many of those)

Can't access /var/log/messages right now, due to broken I/O. Will try
to trigger it again and check for the qc timeout messages..

Stephan
