I've been having problems getting my CD-Recorder to work under RH 6.1 It
was fine under 6.0.  I contacted the authors of the software that I use
(cdrecord & xcdroast) and they said that it looks like a bug in the kernel
scsi code.  I include below both e-mails with the details of the problem.

This is an impossible error.

There must be a bug in the sg.c code in the kernel.
Try to use a different Linux kernel.

Looks like the kernel-driver of your scsi-card is causing problems...
Perhaps see if there are any compile-options for the scsi-driver and
tweak there a little.
No idea otherwise.

Good luck,
