[Bug 64548] Re: System logs fill with cdrom errors (1 GB per 20 minutes)

[kko]

UPDATE: It is happening again as I write this, this time on Dapper, but
with the same device.

This time the first message was "Mar  7 16:00:04 mymachine kernel:
[17190709.372000] cdrom: dropping to old style cdda (sense=b)". The
earlier "sense=4" is now "sense=b", but otherwise identical. However,
this time there was nearly 15 minutes before the repeating error
messages started. They started a while ago, when I started transferring
the rest of my CDs to FLAC, this time through KAudioCreator, and seem
identical to those I met earlier:

"Mar  7 16:28:12 mymachine kernel: [17192397.524000] hdd: packet command error: status=0x51 { DriveReady SeekComplete Error }
Mar  7 16:28:12 mymachine kernel: [17192397.524000] hdd: packet command error: error=0x54 { AbortedCommand LastFailedSense=0x05 }
Mar  7 16:28:12 mymachine kernel: [17192397.524000] ide: failed opcode was: unknown"

The transfer operation proceeds, however, correctly. Two questions that come in mind:
- Why did the drive drop to "old style cdda" half an hour ago? (I'll try to think if I was doing anything special then.)
- I'm now using both drives simultaneously. Can the affected drive's slave status have anything to do with this?
