Kevin, the next step is to fully reverse commit bisect from kernel 4.4 to 4.7-rc5 in order to identify the last bad commit, followed immediately by the first good one. Once this good commit has been identified, it may be reviewed for backporting. Could you please do this following

Kevin, to keep this relevant to upstream, could you please test the latest mainline kernel (4.7-rc5) and advise to the results? ** Tags added: kernel-bug-exist-upstream kernel-bug-exist-upstream-4.6.2 regression-release ** Tags added: needs-bisect -- You received this bug notification because
