--- Comment #1 from stefan.demharter@gmx.net ---
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

Stefan
