Fwd: [Bug 109051] intel_idle.max_cstate=1 required on baytrail to prevent crashes

[Paul Mansfield]

Someone said they had two near identical NUCs bought at different times,
one quite stable, one not, and pondered if it was microcode patching in the
firmware

So this might explain why some people have more luck with their Baytrail
device being stable
