I am glad that it's reproducible for you as well. How did you trigger 
it? Because it seems to only crash under heavy load for me. The system 
has been up since I rebooted last night after the crash and I haven't 
seen any problems. Same thing goes for up until last night when I booted 
the new patch. Even building the new patch didn't seem to be enough to 
trigger it.
