Comment 1 Daniel Vetter 2013-11-07 08:37:56 UTC 
Is this a regression or has the testcase always failed (it was renamed from ZZ_missded_irq recently)?

I test it on earlier kernel. The return code also is 1(run ZZ_missded_irq). It always fail.

Timeout, please retest on latest drm-intel-nightly.

    igt/drv_missed_irq_hang: Increase busy load
    
    The test relies on having to wait upon the GPU at some point and so
    simulating a missed interrupt. If there is insufficient load on the GPU,
    we can complete the task before we even wait.
