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

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

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.
