This seems like a kernel-other-dependent software error.

Most likely you are using a development kernel (2.5.xx). In
this case use a stable kernel (latest is 2.4.19 but 2.4.20
is in release candidacy).

I find that the errors are resolved when using a stable kernel.
My errors in the 2.5.47 kernel appear after about 3-6 MBs of
transfer. Under simulation (speed does not change the
output), this information is reported:

Cdrdao version 1.1.8-pre1 - (C) Andreas Mueller
SCSI interface library - (C) Joerg Schilling
Paranoia DAE library - (C) Monty
