[1.] One line summary of the problem:
During burning of CD onto SCSI driver (using cdrecord) crashes. during
the burn (10% or so) it crashes with "Unable to handle kernel null pointer"
[2.] Full description of the problem/report:
During burning of CD onto SCSI driver (using cdrecord) crashes. during
the burn (10% or so) it crashes with "Unable to handle kernel null pointer" and
dumps a whole lot of things to the screen (flags of some sort, eg "eax=..")
[3.] Keywords (i.e., modules, networking, kernel):
scsi, cd record, null pointer
