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.</pre> </div> <hr> You are receiving this mail because: <ul> <li>You are the QA Contact for the bug.</li> <li>You are on the CC list for the bug.</li> </ul> </body> </html>
