[Bug 1509854] Re: drm:intel_pipe_config_compare [i915]] *ERROR* mismatch in ips_enabled
cropr, the next step is to fully reverse commit bisect from kernel 4.2
to 4.3-rc7 in order to identify the last bad commit, followed
immediately by the first good one. Once this commit has been identified,
then it may be reviewed as a candidate for backporting into your
release. Could you please do this following
https://wiki.ubuntu.com/Kernel/KernelBisection#How_do_I_reverse_bisect_the_upstream_kernel.3F
?
Please note, finding adjacent kernel versions is not fully commit
bisecting.
Thank you for your understanding.
