Hi Jean-Sébastien

After some time of testing with FreeBSD 10.1 and libGL/dri 10.3.3 I can 
now confirm that driver crashes are extremely rare.

I had about 4 crashes in three weeks. And they seem completely random 
meaning I'm not able to reproduce it.

The card doesn't recover, the display just turns black. Is there any not 
to complex way to get debug output of such a crash?

Thanks for your time and sorry about the noise
