If your kernel did crash, then you definitely found a kernel bug.

IF you write in SAO mode and your drive is not broken (use -raw96r
with Lite-ON drives for this reason....), then you may simply 
checksum the complete content of the session. The CD definitely gives you
exactly the same content back that has been in the *.iso file.
