| |
Hi, recently I noticed the following strange behaviour with my laptop (Toshiba Satellite 4300 series):
When I have a CDROM mounted and then suspend/resume, I get errors accessing the files on the CDROM (at least those whose contents are not in the page cache). Applications trying to read get EIO and syslog shows:
Sep 09 12:21:04 click kernel: I/O error: dev 0b:00, sector 292748
and sometimes also
Sep 09 12:26:08 click kernel: SCSI cdrom error : host 0 channel 0 id 0 lun 0 return code = 28000000 Sep 09 12:26:08 click kernel: ILI Current sd0b:00: sense key Illegal Request Sep 09 12:26:08 click kernel: Additional sense indicates Illegal mode for this track Sep 09 12:26:08 click kernel: I/O error: dev 0b:00, sector 315304
Note that I use SCSI over IDE emulation to access the CDROM drive. The problem doesn't show when I switch to "pure" IDE access. Also, even when using IDE SCSI, it's just that accesses via the filesystem fail, reading the device with e.g. dd shows no problems.
Kernel is vanilla 2.4.9-pre4.
Cheers, Roderich
