dmesg output

Did a git-build yesterday to try out the now enabled dri3 on my ppc hardware.
Xorg succesfully starts with dri3 enabled, but after some desktop usage I get
gpu resets or total freezes (machine unaccessable via sshd).

[  295.760807] radeon 0000:f0:10.0: ring 0 stalled for more than 10133msec

Very similar to #94877 but as the card is different (r300 instead of r100),
dri3 instead of dri2, current kernel & mesa-git I decided to file a new bug.</pre>
