I put a dvd in and mounted it. Then rebooted. I saw these messages:
[ 756.539018] pktcdvd: pktcdvd0: writer mapped to sr0
[ 3.744658] sr 3:0:0:0: [sr0] scsi3-mmc drive: 62x/62x writer dvd-ram cd/rw xa/form2 cdda tray
[ 19.585098] pktcdvd: pktcdvd0: writer mapped to sr0
Then removed the DVD and rebooted, back to these:
[ 4.006759] sr 3:0:0:0: [sr0] scsi3-mmc drive: 40x/40x writer dvd-ram cd/rw xa/form2 cdda tray
[ 9.434955] sr 3:0:0:0: [sr0] tag#1 FAILED Result: hostbyte=DID_OK driverbyte=DRIVER_SENSE cmd_age=2s
[ 9.439990] sr 3:0:0:0: [sr0] tag#1 Sense Key : Not Ready [current]
[ 9.444968] sr 3:0:0:0: [sr0] tag#1 Add. Sense: Medium not present - tray closed
[ 9.449918] sr 3:0:0:0: [sr0] tag#1 CDB: Read(10) 28 00 00 07 ff fc 00 00 02 00
[ 9.459897] sr 3:0:0:0: [sr0] tag#18 unaligned transfer
I am starting to consider re-installing, although everything is working,
I don't like the look of it. Perhaps I should just re-install the
kernel?
