Hi,
I'm a using the last cdrecord version (1.11a39) when this oops occurs. I can't sync
my disks with alt-sys-request because we are in interrupt :(
Kernel is build with gcc ersion 2.95.4 20011002 (Debian prerelease). I've two
scsi drives, one scsi cdr and a new one in ide (cdrw). See the dmesg boot below.

This is my new cdrw, my ide setting is the defaut setting so it is not using 32 bits access for the moment.
