I suspect this is caused by the RADEONWaitForIdleMMIO() call Vladimir added to RADEONChooseCursorCRTC() on February 18th. I think this function will be called asynchronously, so the hardware lock isn't held, and another client can keep the engine busy long enough for RADEONWaitForIdleMMIO() to time out, in which case it will try to reset the chip, still without the lock, which would explain the kernel messages about radeon_cp_reset. This is also more likely to happen with SMP, so I think it matches your observations pretty well. :)
Woohoo. We have a likely culprit. Vladimir, does that make sense to you?
