[Bug 1469707] Re: keyboard drops keystrokes occasionally

 

Michael Swierczek, just to advise, the mainline kernel is not supported
as per https://wiki.ubuntu.com/Kernel/MainlineBuilds .

Hence, the next step is to fully reverse commit bisect from kernel 3.19
to 4.1 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.
