Hi Folks,
I am trying to get cd ripping to work on a freshly installed SuSE 9.1 on
IBM thinkpad R50 with dvdram drive.
It works for a while and then hangs. At this point nothing short of a
reboot works. Ripping stop working when the message cdrom: dropping to single frame dma
comes up. The system feels slow for a couple of seconds and then is back
to normal, but no ripping until next reboot
I am running the 2.6.4 compiled by SuSE.
Can you retest with this small debug patch applied.

I did it and started ripping a cd it froze after 9 tracks, though did
not see your message. I was looking at /var/log/messages (see below).
BTW the system got instable and then froze had to power down. It
happened before always after the ripping problem.
Should I aswitch on debug for the cdrom?
Just an idea - can you log vmstat 5 info while doing this burn? Maybe
there's still a little leak in there, so watch the ram usage
(used/free/swap/cache).
Does your drive have dma enabled?
dma was off. I turned it on and now everything is fine I am through the
third cd without a glitch...
Thanks and sorry for being so stupid :)
