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

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

Package: linux-source-2.6.18
Version: 2.6.18.dfsg.1-11
Severity: important


This is similar to 265747, which was determined to be a kernel problem, but this 
is happening with a different kernel version, different package (wodim) and 
different drive.

I insert a blank CD-R disk in the drive.

I run:
  wodim dev=/dev/cdrw /home/john/debian-testing-i386-CD-1.iso

I get:
wodim: No write mode specified.
wodim: Asuming -tao mode.
wodim: Future versions of wodim may have different drive dependent defaults.
Device type    : Removable CD-ROM
Version        : 0
Response Format: 1
Vendor_info    : 'SAMSUNG '
Identification : 'CDRW/DVD SM-308B'
Revision       : 'M002'
Device seems to be: Generic mmc2 DVD-ROM.
Using generic SCSI-3/mmc   CD-R/CD-RW driver (mmc_cdr).
Driver flags   : MMC-2 SWABAUDIO
Supported modes: TAO PACKET SAO SAO/R96R RAW/R16 RAW/R96R

Then it hangs.

For ever.  If I continue to use other applications eventually I get a complete 
system freeze and this also happens with the normal shut down from gnome and I 
have to use ctr-alt-del in a terminal.

I have
CDR_NODMATEST=true
in /etc/environment

The drive reads CDs and DVDs all right.
