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).

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.
