You are running the Linux alpha kernel series (2.6). In this alpha software 
series, frequent unannounced incompatible interface changes are common.

These interface changes make user land commands like cdrecord fail.

If you are using developer grade alpha kernels, you of course need to 
use userland programs that are _newer_ than the kernel and that have already 
been updated to work around the incompatible kernel interface changes.

This version of cdrecord is 14 months old, 14 months older than your kernel!


>/usr/bin/cdrecord: Warning: using inofficial version of libscg 
>(debian-0.8debian2 '@(#)scsitransp.c 1.91 04/06/17 Copyright 
>1988,1995,2000-2004 J. Schilling').

This indicates that you are not using an official version of cdrecord but 
a version that has been bastardized by Debian and that implements bugs that
are not present in the original.

>/usr/bin/cdrecord: Cannot allocate memory. read buffer: scsi sendcmd: no error
>CDB:  3C 00 00 00 00 00 00 FC 00 00
>status: 0x0 (GOOD STATUS)

This is most likely a problem caused by an incompatibility introduced by 
Linux-2.6.16 and the official cdrecord already implements a workaround for 
this imcompatibility....

As it seems that Debian maintainers do not take their users for serious anymore
and did not update cdrtools for a long time, I am no longer sure whether
they still know about the Debian roots and about it's early people Bruce Perens
who did write the Debian social conteact guidelines (see remark at the 
bottom of http://www.opensource.org/docs/definition.php).
Some Debian maintainers recently started to ignore the Debian social contract:
http://www.debian.org/social_contract which is identical to
http://www.opensource.org/docs/definition.php.

I recommend to just use the original from:

        ftp://ftp.berlios.de/pub/cdrecord/alpha/

It is true and (opensource.org aproved) free Opensource Software

Just avoid the versions from Debian that limit your freedom......
