--- Comment #10 from Nicolai Hähnle <nhaehnle at gmail.com> ---
Okay, that's an error during shader compilation - I missed that in the log you
posted. Seems like a very large shader runs into problem with branch lowering,
probably something that's not properly implemented in LLVM yet.

Can you run with the environment variable R600_DEBUG=ps,vs,gs,tcs,tes set and
post the log output? (This allows us to extract the problematic shader before
it is passed to LLVM - the output will be rather large.)

P.S.: For future reference, it's helpful to use `ps f` (maybe in a combination
like ps afx) to get a tree view of processes. Together with the CPU time spent
in each process, it's a good help in figuring out which is the correct process
to attach to.
