I'd bet on runtime pm or some other power saving feature in amdgpu
shutting the interrupt handling down before we've handled all the
interrupts. That would then result in a stuck fence.

Do we already know which fence is stuck? All the debuggin on the
dma_fence_wait side is just looking at the messenger, this isn't the
source of the problem.
