Hi, With 4.0.0-rc6 kernel (enable_cmd_parser=1 as default), the HSW issue also exists on Release_v1.0 branch:1.0.1, 1.0.2, and the latest git. But it is OK on 1.0.0 (git-59142eb). The bisected commit is also git-7ecc5b9d.

Mengmeng, could you help to test Release_v1.0 branch with 4.0.0-rc6 kernel? Maybe bisect on beignet side to find out the first bad commit? Thanks. On Fri, Apr 10, 2015 at 12:01:48PM +0100, Rebecca N.
