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<br>
issue.<br>

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.<br>
<br>

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.<br>
