There is a known issue in some versions of linux kernel which enable register whitelist feature but miss some necessary registers which are required for beignet. The problematic version are around 3.15 and 3.16 which have commit f0a346b... but haven't commit c9224f... If it is the case, you can apply c9224f... manually and rebuild the kernel or just disable the parse command by invoke the following command (use Ubuntu as an example): `# echo 0 > /sys/module/i915/parameters/enable_cmd_parser` On Mon, Oct 20, 2014 at 12:47:41PM +0800, Zhigang Gong wrote: > Did you apply the kernel patch for HSW mentioned in the README.md? > > * Some unit test cases, maybe 20 to 30, fail on 4th Generation (HSW) platform. > The 4th Generation Intel Core Processors's support requires some Linux kernel > modification.

The screen freezes for about 5 seconds, then the errors show up. I tried running "echo -n 0 > /sys/module/i915/parameters/enable_hangcheck" before executing "pyrit selfcheck", but that freezes the screen until reboot (I waited about 10 minutes).
