--- Comment #7 from Christoph Haag ---
Created attachment 117771
--> https://bugzilla.kernel.org/attachment.cgi?id=117771&action=edit
Same as "117761: dmesg with drm-fixes-3.12-radeon-poweroff branch", but with
rmmod radeon and modprobe radeon
Okay, I exited X and from a tty did rmmod radeon. It produced the same error in
dmesg than it does on 3.13, see attached file...
Then with modprobe radeon I got the GPU lockup CP stall for more than
10000msec, but interestingly only once and then it worked.
The radeon gpu was at DynOff then.
As soon as I started X, the gpu was powered on to DynPwr again. Not even
configured as provideroffloadsink or so, just the X startup and presumably
hardware detection powered it up and it does not go back to DynOff.
But again, knowing that runpm itself works without errors is encouraging.
