Bug#416388: linux-source-2.6.18: Wodim hangs and system may freeze

[John Talbut <john@dpets.demon.co.uk>]

Now on kernel 2.6.22 and still getting the same problem.

I do:
~$ wodim dev=/dev/cdrw "/data/Our Old Documents 2005-07 oncd"

I get:

wodim: No write mode specified.
wodim: Asuming -tao mode.
wodim: Future versions of wodim may have different drive dependent defaults.
wodim: Operation not permitted. Warning: Cannot raise RLIMIT_MEMLOCK 
limits.Device type    : Removable CD-ROM

Syslog reads after the hang:

etc.

Is there any reason to think that 2.6.23 would be any different?  (I am using 
the testing distribution, I would rather not get involved in backporting.)
