Doesn't sound like it he mentions radeon drm module which is open...

OK. Well from the task trace, X is getting stuck on a locked page. And
as it is never getting unlocked, I'd be almost positive it comes from
a driver's nopage. I know some ATI driver did that in the past. Would
the radeon drm module do anything similar?
