[Bug 45880] Xorg crash with ColorTiling2D patch (r600g)

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 patch partially work.

glxgears now work ok, but vmware (with 3d acceleration) cause Xorg crashed. (file "kern2.log" attached)

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.
