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.Attached is a v2 of the patch, for reference. 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

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.
