Hello everyone,

it looks like this does indeed fix the fbc problem. I applied the
patch, and did some testing. I am using a Dell Latitude e6420, this is
my setup:

brotscheibe brot # cat /sys/kernel/debug/dri/0/i915_fbc_status
FBC enabled
brotscheibe brot # uname -a
Linux brotscheibe 3.4.0-rc2+ #52 SMP PREEMPT Mon Apr 9 21:51:57 CEST
2012 x86_64 Intel(R) Core(TM) i5-2540M CPU @ 2.60GHz GenuineIntel
GNU/Linux

After nearly an hour of testing, i got no hangs. Even when using rxvt
and "while (true) do dmesg; done".

I will do more testing tomorrow, but i dont think anything will fail.

You can add my tested-by: Michael "brot" Groh <michael.groh at minad.de>

Thanks for your work and have a nice day,
Michael
