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.
Basically, OpenCL support for VI isn't implemented yet.
What is missing? Can it at least not crash?

Is it possible to work around the lock? I ran into the same issue, when I tried running clpeak ( https://github.com/krrishnarraj/clpeak ) on kernel 4.4.0-rc7 with current mesa-git and an R9 380X. kernel: amdgpu 0000:01:00.0: IH ring buffer overflow (0x000C01D0, 0x00000B40, 0x000001E0) kernel: amdgpu 0000:01:00.0: GPU fault detected: 147 0x05f88802 kernel: amdgpu 0000:01:00.0: VM_CONTEXT1_PROTECTION_FAULT_ADDR 0x0004009C kernel: amdgpu 0000:01:00.0: VM_CONTEXT1_PROTECTION_FAULT_STATUS 0x0A088002 kernel: VM fault (0x02, vmid 5) at page 262300, read from 'TC9' (0x54433900) (136)
After upgrading to current llvm 3.8-git (2921ff9ffcfd09db1c), the program ran
fine:
