Thanks for testing. Other issues are probably unrelated, so I'll send the last version of the patch to Dave.

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.

[drm] radeon: finishing device.

radeon 0000:01:00.0: ffff88024f2f6000 unpin not necessary

By the way, sometimes my r8169 ethernet controller does not survive suspend/hibernation (does not detect link). rmmod/modprobe helps. I don't know if this is related.
