Langdon,

I have the same problem, also with F7 on an x86_64 system.  I've tried all
the development kernels for F7, I also tried the i386 version of F7, and I
even tried going back to the current FC6 kernel and no luck, the system
still crashes.  Nothing comes out on the console (using a serial console) 
occasionally I'll get an entry in /var/log/mcelog but they did not
coincide with the system crash.

This system ran stable as a rock on FC6 and as of last night I went back
to FC6.  When reinstalling the system I reformatted all the partitions
except for /home.

The system is an Intel DG965RY motherboard and a Pentium D processor.

Just to make sure something didn't happen to the system between the
upgrades I ran for 9+ hrs memtest86 v3.3, it found no errors.
