After between 10 and 60 minutes of uptime, my DVD drive begins to show
strange behaviour:
- an icon appears on the KDE desktop showing either a data CD-ROM
or an audio CD (although the tray is empty and closed)
- in /var/log/kern.log, these messages appear in large numbers:
Dec 18 10:28:00 guitar2 kernel: hda: cdrom_pc_intr: The drive appears
confused (ireason = 0x01). Trying to recover by ending request.
Dec 18 10:28:00 guitar2 kernel: hda: status error: status=0x58 { DriveReady
SeekComplete DataRequest }
Dec 18 10:28:00 guitar2 kernel: ide: failed opcode was: unknown
Dec 18 10:28:00 guitar2 kernel: hda: drive not ready for command
Dec 18 10:28:02 guitar2 kernel: hda: status error: status=0x58 { DriveReady
SeekComplete DataRequest }
Dec 18 10:28:02 guitar2 kernel: ide: failed opcode was: unknown
At this stage, the drive becomes unusable, while it it is working fine
otherwise.
A reboot "fixes" the problem, until the next occurence.
I am not sure where to report this bug - maybe for linux-image-2.6.23-1-amd64?
Has anybody seen something like this before?
Any hints how I could rule out faulty hardware?
I am running debian testing (amd64), with both 64-bit kernel and userspace.
The problem appears with any of the 2.6.18-5 (stable), 2.6.22-3 (testing)
and 2.6.23-1 (unstable) kernel packages.
my hardware:
- PLEXTOR DVDR PX-760A, firmware 1.07
(restored to original Plextor firmware for this bug report)
- mainboard Gigabyte 965P-S3, with this IDE controller:
03:00.1 IDE interface: JMicron Technologies, Inc. JMicron 20360/20363 AHCI
Controller (rev 02)
Any further information I should provide?
Thanks,
Mirko
