          Priority: medium
            Bug ID: 69328
          Assignee: dri-devel at lists.freedesktop.org
           Summary: Recoverable and unrecoverable lockups with
                    opencl-example on trinity APU
          Severity: normal
    Classification: Unclassified
                OS: Linux (All)
          Reporter: slicksam at gmx.com
          Hardware: x86-64 (AMD64)
            Status: NEW
           Version: git
         Component: Drivers/DRI/R600
           Product: Mesa

Software in use:

Up to date mesa, llvm, clang, libclc, firmware, as of 20130910.  Gentoo's Linux
3.11. opencl-example-12905ac620b83713b07ece763ff3c36fb3c2e7e5.

Hardware in use:  AMD A8 5600K APU (Radeon HD 7560D, Aruba), 32GB system RAM,
Biostar Hi-Fi A85W motherboard.

Steps to reproduce: 

Run hello_world program from opencl-example.  First run works correctly. 
Second run either completely locks up the machine or locks up the GPU (which
recovers after a short time).  Same behavior for other tests - the first test
completes and the second causes problems.


This is what the second opencl-example run looks like:

localhost opencl-example-12905ac620b83713b07ece763ff3c36fb3c2e7e5 #
./hello_world 
There are 1 platforms.
There are 1 GPU devices.
clCreateContext() succeeded.
clCreateCommandQueue() succeeded.
clCreateProgramWithSource() suceeded.
clBuildProgram() suceeded.
clCreateKernel() suceeded.
clCreateBuffer() succeeded.
clSetKernelArg() succeeded.
clEnqueueNDRangeKernel() suceeded.
((( 10 second hang here, or forever if the machine is toast )))
clEnqueueReadBuffer() suceeded.
pi = 3.141590


And, here is the dmesg output from the recoverable lockups:
