If that is what is going on, there is nothing linux can do about it;
it's a limitation of the hardware. The IDE controller can only accept
one command at a time, so if that command takes a while to complete, the
other drive on the same channel can not be accessed until the first
command completes.

If the system doesn't come back though after sufficient time has gone by
for the burn to complete, then this is probably not what is happening.
I'd suggest using magic-sysreq to force an unmount and reboot, then see
if there's anything in the logs.

Perhaps a good test would be to try cdrecord from the command line to
blank the cd, to avoid issues to do with X, xcdroast, etc. Just the
minimum you can have.

Also what command line does xcdroast generate for the blanking?
