[Bug 1531630] Re: Unusable after upgrade linux from 3.16 to 4.3


Andrew, the next step is to fully reverse commit bisect from kernel 4.3
to 4.4-rc8 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

Please note, finding adjacent kernel versions is not fully commit

After the fix commit (not kernel version) has been identified, then
please mark this report Status Confirmed.

Thank you for your understanding.
