The games RAGE and Wolfenstein The New Order (using Wine) hangs after a short while in the menu.
Trying older Mesa releases (and a hacked Wine to work around the need for a compatibility context) 17.3.9 does not have this issue.
Bisecting lead to
radeonsi: avoid syncing the driver thread in si_fence_finish
It is really only required when we need to flush for deferred fences.
It's not possibly to revert that commit cleanly on 18.2.0, but moving back "ctx = threaded_context_unwrap_sync(ctx);" to its original place is enough to get rid of the hang.
Thanks for another quality bug report!
I've sent a patch to revert the change for now.

Revert "radeonsi: avoid syncing the driver thread in si_fence_finish"
This reverts commit bc65dcab3bc48673ff6180afb036561a4b8b1119.
This was manually reverted. Reverting stops the menu hanging in
some id tech games such as RAGE and Wolfenstein The New Order.
