Okay, this sounds more likely like a kernel problem than a cdrecord
problem. If you have some time, please try with combinations of
following factors to find the reason of the trouble:

 - enable swap (does not fight the root of the problems but gives you
   more time to experiment)
 - use a non-SMP kernel
 - try kernel 2.6.7
 - run cdrecord.shm instead of cdrecord or cdrecord.mmap (note that
   there are some limits with .shm, see README.Debian)

AFAICS there were no such reports and that's what it is confusing. I do
not count on much help from the upstream author there.

Thanks for your efforts,
Eduard.
