Hi,

I have todays CURRENT. My machine is Dell Latitude D620 with 945GM 
graphics card.
When I try to run xorg 7.2, my machine hangs and on serial console it 
showed:

uma_zalloc_arg: zone "64" with the following non-sleepable locks held:
exclusive sleep mutex drm device r = 0 (0xc3c06cd8) locked _at_
