Previous kernel 2.6.11-1.1369_FC4 works without crashing. It does however print the following messages when mounting: hdb: command error: status=0x51 { DriveReady SeekComplete Error } hdb: command error: error=0x54 { AbortedCommand LastFailedSense=0x05 } ide: failed opcode was: unknown ATAPI device hdb: Error: Illegal request -- (Sense key=0x05) Read of scrambled sector without authentication -- (asc=0x6f, ascq=0x03) The failed "Read 10" packet command was: "28 00 00 3b 3b a0 00 00 02 00 00 00 00 00 00 00 " end_request: I/O error, dev hdb, sector 15527552 Buffer I/O error on device hdb, logical block 3881888 Buffer I/O error on device hdb, logical block 3881889 hdb: command error: status=0x51 { DriveReady SeekComplete Error } hdb: command error: error=0x54 { AbortedCommand LastFailedSense=0x05 } ide: failed opcode was: unknown ATAPI device hdb: Error: Illegal request -- (Sense key=0x05) Read of scrambled sector without authentication -- (asc=0x6f, ascq=0x03) The failed "Read 10" packet command was: "28 00 00 3b 3b a0 00 00 02 00 00 00 00 00 00 00 " end_request: I/O error, dev hdb, sector 15527552 Buffer I/O error on device hdb, logical block 3881888 Buffer I/O error on device hdb, logical block 3881889
I verified that this happens when attempting to mount a blank DVD, but not when mounting an already written data DVD. It also happens for me when trying to mount a video DVD. I reported this in bug #162295.
