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.

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.

If was broken for me since sarge to start with.

As you may read on that reports, the problem is DMA. Did you try to
switch off it on your opto-drive (hdparm -d0 /dev/cd-rw)? I always
do this, before writing anything optical.

If this helps, then kernel developers don't care much to debug and test
it. Maybe because DMA is not important for this things. I doubt recording
speed may be safely more than x16 (=2.4M/s), due to quality of storage.

Thus, implementing things like DMA tests and using it in cdrecord is
a bad idea, IMHO.

Thanks, Oleg, that has made a bit of difference.

I did:
hdparm -d0 /dev/cdrw
in a root terminal

and it responded with:
/dev/cdrw:
  setting using_dma to 0 (off)
  HDIO_SET_DMA failed: Operation not permitted
  using_dma    =  0 (off)


I then proceeded as before.  Wodim hung as before, but then everything unfroze 
when I pressed the eject button on the cdrw drive.  It still did not write, nor 
eject, but I have got a message from Wodim indicating that it is not recognising 
the blank disk.

John

Well, it can be wrong driver, who does not want to set DMA.

Anyway, it seems, by "(*) Leave as NEW" status, unsolved in upstream (:

http://bugzilla.kernel.org/show_bug.cgi?id=6745

I think, boot log, hdparm /dev/cdrw, hdparm -i /dev/cdrw would be good
to have there.

Also, please try latest experimental (http://wiki.debian.org/DebianKernel)
or upstream (kernel.org linux2.6.21-rc5-git2) kernel.

OK, I am now on kernel 2.6.21 and I am getting the same problem.  Syslog now 
reads after the hang:

etc.

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:

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.)
