 Update: I found info suggesting cstate limits of 0,1 & 6(default) are valid, maybe 3, but probably not 2.

I had to boot my CHI into the OEM. When I resumed linux, I omitted the cstate kernel argument, as a sanity check. My 4.2.6 froze within 5 minutes (browsing internet eagle cam). Otherwise, still no freezes when I set intel_idle.max_cstate=1. (~10 days so far)

It looks like I can reproduce one type of freeze readily, so if y'all have [baytrail cstate management] 4.2.x patches to beta test, let me know. I can also test 4.1.1x or 4.3.x patches but those freeze rates are less "dependable." I won't test 4.4-rcx until wifi (or USB wifi dongle) starts working again in the stock kernel.
