Hi,
I'm not sure which package would be causing this issue -
Symptoms: I can read and burn dvds consistently on my machines internal drive without an issue, but after a period, the discs stop being recognised, and dmesg spits out the following error when a blank dvd is inserted:
$ dmesg
...
[540928.561563] cdrom: This disc doesn't have any tracks I recognize!
[540928.685580] sr 1:0:0:0: [sr0] Result: hostbyte=DID_OK driverbyte=

[540928.685592] end_request: I/O error, dev sr0, sector 0
[540928.685595] Buffer I/O error on device sr0, logical block 0
At this point, if I plug in an external dvd-burner and insert the blank dvd into it, the same error appears for this new drive:
$ dmesg
...

which implies that the entire optical device subsystem has gotten itself in a tangle.
Rebooting allows both the drives to operate as per normal again - the period it took for this failure was 6 days of constant uptime (no suspend/hibernate), burning ~5 DVDs a day. Prior to this it was happening every 2-3 days under the same conditions, so the period for failure doesn't seem to be consistent.
Hardware Info:
From lshw: The internal drive (sata connected)
*-cdrom
bus info: scsi@1:0.0.0
The USB drive:
*-scsi:1
physical id: 2
bus info: usb@2:1
logical name: scsi7
*-cdrom
bus info: scsi@7:0.0.0
*-medium
Let me know if you need more info -

Bernie
As a follow up, I've had this issue crop up 3 times today already (necessitating a reboot each time to resolve)
