[Bug 92087] [Radeon/Tonga] lockup in valley demo

https://bugs.freedesktop.org/show_bug.cgi?id=92087

--- Comment #1 from Andy Furniss adf.lists@gmail.com --- There are a couple of related bugs already open.

The VM fault seems to have appeared with more recent kernels, I can get those now even without locking.

If you leave valley for a couple of minutes after lock you will likely get a hung task trace like those in the bugs below (Though not a GPU reset as that is not enabled on more recent kernels)

It would probably be best to mark this bug a DUP of one of these.
