I've got Bay Trail based Asus X553MA and I've been experiencing daily hangs with kernels beginning from 4.2-rc1. I haven't had any problems with 4.1.x kernels and using 4.1.13 I've gotten constant 5+ day uptimes since November (I had to at least suspend it once per week for traveling but during Christmas longest uptime was 11 days). Now I did bisection beginning with marking 4.2-rc1 as bad and 4.1.0 as good and found out that it was this commit: [8fb55197e64d5988ec57b54e973daeea72c3f2ff] drm/i915: Agressive downclocking on Baytrail causing the hangs. 4.4-rc8 hanged in less than hour. After I reversed the patch from it and commented out lines containing related fields from i915_debugfs.c I now seem to have stable 4.4-rc8. _______________________________________________ Intel-gfx mailing list Intel-gfx@xxxxxxxxxxxxxxxxxxxxx http://lists.freedesktop.org/mailman/listinfo/intel-gfx
