Regarding the debugging of lockups I had the following on my "in mind

1. Rework the chip specific lockup detection code a bit more and
probably clean it up a bit.
2. Make the timeout a module parameter, cause compute task sometimes
block a ring for more than 10 seconds.
A better solution for that would be to improve the detection of the GPU
making progress, also for graphics operations. We should try to reduce
the timeout rather than making it even larger.
Well, let's call it a more complete solution.
Since making the parameter configurable don't necessary means we are
going to increase it. I usually set it to zero now, since that disables
lockup detection at all and enables me to dig into the reason for
something getting stuck.
