I have a similar issue with a 'SAMSUNG SC-140B' CDROM in 2.4.latest and also 2.6.latest.
hdparm -d0 /dev/hdc + hdparm -X8 /dev/hdc fixes it :(
I updated the CDROM firmware, no change. With 2.4.33-pre1: syslog: Jan 2 09:02:33 niner kernel: hdc: drive_cmd: status=0x51 { DriveReady SeekComplete Error } Jan 2 09:02:33 niner kernel: hdc: drive_cmd: error=0x04Aborted Command Jan 2 09:02:52 niner kernel: hdc: CHECK for good STATUS Jan 2 09:03:26 niner kernel: hdc: media error (bad sector): status=0x51 { DriveReady SeekComplete Error }
CDROM is stuck at the moment: root 279 0.0 0.3 1688 612 ttyp1 D+ 09:03 0:00 mount /dev/hdc /mnt/cdrom/
Should I ignore this and replace the CDROM or blacklist the thing?
The box here is a s/h thing I've had for only a month, no history for you. What other testing you suggest to narrow the thing down?
Hmm, while I wrote this, the driver recovered, syslog: Jan 2 09:18:28 niner kernel: hdc: media error (bad sector): error=0x34 Jan 2 09:18:28 niner kernel: end_request: I/O error, dev 16:00 (hdc), sector 60 Jan 2 09:18:43 niner kernel: hdc: DMA interrupt recovery Jan 2 09:18:43 niner kernel: hdc: lost interrupt Jan 2 09:18:43 niner kernel: hdc: status timeout: status=0xd0 { Busy } Jan 2 09:18:43 niner kernel: hdc: status timeout: error=0x00 Jan 2 09:18:43 niner kernel: hdc: drive not ready for command Jan 2 09:18:43 niner kernel: hdc: ATAPI reset complete
Box info: http://bugsplatter.mine.nu/test/boxen/niner/ this is same box I tickled an oops out of under 2.6.14.5 playing with the CDROM.
