<pre>I've got a muxed system with intel+radeon graphics card.
If I switch off the device, unload the radeon module and reload it I get the
following errors and can't use the device until I restart the system:
[ 108.234152] [drm:r600_ring_test] *ERROR* radeon: ring 0 test failed
(scratch(0x8504)=0xFFFFFFFF)
[ 108.234199] radeon 0000:02:00.0: disabling GPU acceleration
[ 113.249241] [drm:atom_op_jump] *ERROR* atombios stuck in loop for more than
5secs aborting
[ 113.249286] [drm:atom_execute_table_locked] *ERROR* atombios stuck executing
E192 (len 2328, WS 4, PS 4) @ 0xE7E8
... snip ...
[ 141.216044] BUG: soft lockup - CPU#1 stuck for 22s! [modprobe:4068]
[ 143.411205] [drm:atom_op_jump] *ERROR* atombios stuck in loop for more than

[ 143.411287] [drm:atom_execute_table_locked] *ERROR* atombios stuck executing
CC36 (len 62, WS 0, PS 0) @ 0xCC52
Steps to reproduce:
In /sys/kernel/debug/vgaswitcheroo:
echo OFF > switch
rmmod radeon
modprobe radeon
