The panic backtrace doesn't look obviously related to the radeon driver — all
the symptoms sound like something might be scribbling more or less randomly
over memory.
I wonder if the line
mtrr: type mismatch for e0000000,10000000 old: write-back new: write-combining
in dmesg might be relevant. Can you try resolving that, e.g. using
https://linuxindetails.wordpress.com/2010/06/27/mtrr-type-mismatch-for-e000000010000000-old-write-back-new-write-combining/
and see if that helps? Might be interesting seeing the contents of /proc/mtrr
before and afterwards (if it changes).
