Description Martin Peres 2017-03-17 11:17:40 UTC 
We got "*ERROR* CPU pipe B FIFO underrun" in dmesg when running igt@drv_module_reload@basic-reload-final on CI_DRM_2337.

Full results: https://intel-gfx-ci.01.org/CI/CI_DRM_2337/fi-skl-6770hq/igt@drv_module_reload@basic-reload-final.html
Comment 1 Martin Peres 2017-03-23 11:51:17 UTC 
Failure rate 2/49 run(s) (4%)

Does not seem to have happened since CI_DRM_2337. Raising the priority anyway so as to get developer feedback on this!
