Byt does have a known hard hang somewhere between the punit and cstates. Maybe we should use intel_idle.max_cstate=1 for the farm for stability reasons?

This also looks like suspicious system hang:

Has anybody tried Chris' suggestion above: "Maybe we should use intel_idle.max_cstate=1 for the farm for stability reasons?"

Changing to NEEDINFO while waiting for the answer to the above question.

Tomi, it seems this never was applied to the grub command line (https://intel-gfx-ci.01.org/tree/drm-tip/CI_DRM_4919/fi-byt-clapper/boot0.log).

Would it be possible to add it?

Ping?

Added option intel_idle.max_cstate=1 for fi-byt-clapper, added host to https://intel-gfx-ci.01.org/hardware.html

Thanks!

Moving to medium since it's a meta-bug of sorts.
