What version of xf86-video-intel? I'm having trouble since I upgraded  
xf86-video-i810, which is an older version of the intel driver, from 1.6.x  
to 1.7.x and a colleague had trouble with the 2.x version of the  
xf86-video-intel driver.
My trouble is a hanging system (I never waited for it to come back) and  
then ctrl-alt-F1 (to console) gives a panic a lot of times. I just  
prepared my machinde for a crash dump. So maybe next panic I have one.

Maybe downgrading to 1.6.x helps me again. After the next panic I'll try  
that. But maybe it helps you also.

I upgrade my RELENG_7 about every week, so it's fairly recent.
