Here's your output: kazimir:~# mount /cdrom sr 1:0:0:0: [sr0] Result: hostbyte=3D0x00 driverbyte=3D0x08 sr 1:0:0:0: [sr0] Sense Key : 0x5 [current] sr 1:0:0:0: [sr0] <> ASC=3D0xa8 ASCQ=3D0x1ASC=3D0xa8 ASCQ=3D0x1 sr 1:0:0:0: [sr0] CDB: cdb[0]=3D0x28: 28 00 00 00 00 10 00 00 02 00 end_request: I/O error, dev sr0, sector 64 Buffer I/O error on device sr0, logical block 8 The kernel tried to read some sectors off the disk (command 0x28) and=20 the drive returned an error. ASC of 0xa8 is a vendor-specific error=20 code, so only Pioneer can likely say what that error means. You're sure that 2.6.22 is still able to successfully access this drive= ?=20 Any unusual dmesg output there? The fact that it doesn't seem to work properly in Windows either does= =20 seem to suggest a drive fault.
