Subjectbuffer io error on device sr0?
Date
I'm not sure which version it started, but it seems at least 2.6.32-rc3-git2 
has issues with detecting blank DVDR disks.

[220595.198654] cdrom: This disc doesn't have any tracks I recognize!
[220595.298488] sr 3:0:0:0: [sr0] Unhandled sense code
[220595.298492] sr 3:0:0:0: [sr0] Result: hostbyte=DID_OK
driverbyte=DRIVER_SENSE
[220595.298496] sr 3:0:0:0: [sr0] Sense Key : Blank Check [current]
[220595.298501] sr 3:0:0:0: [sr0] Add. Sense: No additional sense information
[220595.298505] sr 3:0:0:0: [sr0] CDB: Read(10): 28 00 00 00 00 00 00 00 01 00
[220595.298514] end_request: I/O error, dev sr0, sector 0

Unless its supposed to be this way. Although I didn't receive any kind of
notification when inserting the disk, as I used to (could be a hal/kde error,
but the logs in dmesg seem to hint otherwise).
