| |
Hi,
just tried the new 2.5.1-pre3 and got the following oops when trying to burn a cd (ide-cd/rw with ide-scsi emulation).
I Hope this is some useful information.
____ ksymoops 2.4.3 on i586 2.5.1-pre3. Options used -V (default) -k /proc/ksyms (default) -l /proc/modules (default) -o /lib/modules/2.5.1-pre3/ (default) -m /boot/System.map-2.5.1-pre3 (default)
Warning: You did not tell me where to find symbol information. I will assume that the log matches the kernel and modules that are running right now and I'll use the default options above for symbol resolution. If the current kernel and/or modules do not match the log, you can get more accurate output by telling me the kernel version and where to find map, modules, ksyms etc. ksymoops -h explains the options.

1 warning issued. Results may not be reliable. ____
After the oops the following message appeared in syslog:
Nov 29 18:06:01 enterprise kernel: <6>scsi: device set offline - command error recover failed: host 0 channel 0 id 0 lun 0
____
lsmod shows no loaded ide-scsi or cdrom modules, so the oops happened before loading them.

Please CC: me in replies or if you need further information as I'm not subscribed to l-k.
Cheers,
