For all my tests I use KMS all the time.

Normally I can load and unload rt2800pci dozens of times without a problem.
However if I unload it after "ifconfig wlan0 up" my GPU gets unstable.

When I tried to modprobe rt2800pci after 4th GPU softreset I got lock up and
machine selt-reboot. After rebooting I saw BIOS warning that last booting ended
with "sync flood" (I also got this warning in another radeon bug when it tried
to divide by 0).
