BzukTuk 2016-02-01 22:06:32 UTC Created attachment 202701 [details] Kernel bisection between v4.2 v4.1 for sudden freezes
Hi, small update. My first bisect was from 4.1 to 4.2-rc1 and as first bad commit [cf5d8a46a001c9421c7397699db55f962e0410fc] was flagged. But I was not so sure that i did the bisection properly. So today I made second bisection - git bisect start v4.2 v4.1. Bisection process went without problem/confusion/doubt (as my first attempt did). Last git bisect was good on commit cf5d8a46a001c9421c7397699db55f962e0410fc (after 90 minutes of glxgears and vlc). Git pointed that first bad commit was: [8fb55197e64d5988ec57b54e973daeea72c3f2ff] drm/i915: Agressive downclocking on Baytrail then from commit cf5d8a46.. I cherry-picked 8fb55197 and this kernel froze after 3 minutes. More cherry-picking/testing tomorrow. Sorry if my previous post made confusion/unnecessary work.
