Ching, there were improvements pushed in kernel and Beignet that will benefit to your system, so please re-test with latest kernel & Beignet to see if this issue is still occurring. In that last case, please attached new gpu crash dump and kernel log.

Timeout. Assuming that it is fixed by now. If this is not the case, please re-test with latest kernel & Beignet to see if this issue is still occurring since there were improvements pushed in kernel and Beignet that will benefit to your system.
