[Bug 1492764] Re: [drm:intel_pipe_config_compare [i915]] *ERROR* mismatch in ips_enabled (expected 1, found 0)
The error is gone with 4.3, but what I noticed is higher load average values with 4.3 kernel driver?
I have both Ubuntu 14.04 and Ubuntu 15. 10 (4.2. and 4.3. kernel installed) and all three load average value is higher (within the limit, but higher). Is this some kind of a problem?
