Hi Ilija,
Thanks for testing. Other issues are probably unrelated, so I'll send the last version of the patch to Dave.
I came across another problem which seems related. rmmod radeon works, however, modprobe radeon afterwards results in a crash (divide error), see attachment. Best, Marco On 02.04.2013 13:23, Ilija Hadzic wrote:

I would appreciate if the original reporter or you tested it in lieu of your proposed patch and let me know if it fixes your issue. The patch works for me. echo 3 > /proc/sys/vm/drop_caches as well as rmmod radeon do not end up in a crash anymore. However, I have still no clue why one of these makes drm_open to fail. On rmmod radeon I get the following log messages. If don't know if the 'unpin not necessary' has anything to do with it.

I don't know if this is related.
