           Summary: [radeonsi] Tonga (Radeon R9 380) hangs on running
                    hello world OpenCL program
           Product: Mesa
           Version: git
          Hardware: x86-64 (AMD64)
                OS: Linux (All)

I'm running a hello world PyOpenCL program from here:
http://documen.tician.de/pyopencl/ I get the same issue with a different OpenCL
program, e.g. one from bug 93370.

The message shown in the console is the same as bug 93264, but without the VM
line:

amdgpu 0000:01:00.0: GPU fault detected: 147 0x04588402
amdgpu 0000:01:00.0:   VM_CONTEXT1_PROECTION_FAULT_ADDR   0x0004008B
amdgpu 0000:01:00.0:   VM_CONTEXT1_PROECTION_FAULT_STATUS 0x08084002

The system is unresponsive and one has to do hard reset.

I tried reverting to one commit before c0a189c3792865257c1383f176e5401373ed2270
mentioned in the bug 93264, that is 26ddca196954ccfa697102b46118956ad616073a.
However, this did not fix the problem.
