Card id rv670 AGP, running git xorg, ddx, mesa, libdrm and drt kernel.
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

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.
V2 validate BO with no_wait = true
V3 don't derefence bo->mem.mm_node as it's not NULL only for
VRAM or GTT
V4 update to splitted no_wait ttm change
V5 update to new balanced io_mem_reserve/free change
V6 callback is responsible for iomapping memory

More info - I am not enabling dynpm for these tests.
In dmesg after the signal 7 X shutdown I am seeing -
vmap allocation for size 8192 failed: use vmalloc=<size> to increase size.
vmap allocation for size 49152 failed: use vmalloc=<size> to increase size.
This one was triggered by running glxgears for about 10 seconds.
