Michel, what are the consequences of removing this?
Hmm. Things are slightly compilcated by the fact that this code has been reworked since this change was made. To get rid of the lockup on the dri trunk I have to use the attached patch. It's a little heavy handed...
It basically disables interrupts AFAICS.
No - they still seem to work, which makes sense as they are turned on in the drm module (which also writes to RADEON_GEN_INT_CONTROL).
