Looks like a similar issue, if you could verify a workaround: in mesa, src/gallium/winsys/radeon/drm/radeon_drm_winsys.c change all assignments of r600_virtual_address to FALSE ws->info.r600_virtual_address = FALSE;
The workaround work ok
I pushed a fix please confirm that it also works for you
The patch partially work. glxgears now work ok, but vmware (with 3d acceleration) cause Xorg crashed. (file "kern2.log" attached)
Created attachment 57121 [details] crash log after fix applied
cayman fix pushed to mesa which should be enough on its own, kernel fix is in the pipe

(In reply to comment #6) > cayman fix pushed to mesa which should be enough on its own, kernel fix is in > the pipe The mesa patch is ok. Do you want me to test the kernel fix too? If it is simply to apply, i can help.
No need to test the kernel patch. The kernel patch is just to fix the segfault issue in casse of lockup. The mesa patch is enough on its own for your issue. Closing
