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..
