I've hit a couple of things with radeon as well.. the first was this: http://lkml.org/lkml/2010/6/6/172 (if your hitting this issue, then the patch should work and/or it should already be in the main tree).
then a few days ago hit another: https://bugzilla.kernel.org/show_bug.cgi?id=16335 (keep in mind still uncertain on a fix for this, reverting the commit gets me up and running(I created a patch, but an umsure if it's a right solution)).
if none of these are what your hitting, then maybe(if you can) do a bisect on this!
