[OOPS] ide-scsi

I have a special cdimage which cdrdao can't handle very well.
Cdrdao starts the burning, after a minute the cdrecorder stops
and cdrdao can only be killed.

After this, when something touches the cdrecorder, come the
'scsi: aborting command due to timeout' messages. After this
sysrq-s or sysrq-u usualy triggers the oops, but sometimes
it's only triggered by the shutdown process.

Tried with kernel 2.4.19-rc3-ac5 and 2.4.19-ac4: same results
Later I will check older and not -ac kernels.

Here is the output of ksymoops:
