Yesterdays DRT was fine for me, but after todays commits I am getting kicked out of X with a backtrace that looks like below. The trace varies from 3 down depending on what I was doing when triggering it, the one included was running x11perf -putimage500. I can't restart X after this a it just gets another signal 7. Happens with both agp gart and pcie gart. Git bisect came up with - b562614485ca2247384f540c859e00357fe7adcb is first bad commit commit b562614485ca2247384f540c859e00357fe7adcb Author: Jerome Glisse Date: Wed Apr 7 10:21:24 2010 +0000 drm/radeon/kms: add support for new fault callback V6 This add the support for the new fault callback and also the infrastructure for supporting unmappable VRAM.
