[Kernel-packages] [Bug 1401624] Re: kernel WARNINGs when disabling WiFi with RF kill switch on Intel chip
Laurent Bonnaud, could you please advise to what usage impact this crash has on using Ubuntu? As well, the next step is to fully reverse commit bisect from kernel 3.16 to 3.18 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.

[Kernel-packages] [Bug 1401624] Re: kernel WARNINGs when disabling WiFi with RF kill switch on Intel chip
Did this issue occur in a previous version of Ubuntu, or is this a new issue? Would it be possible for you to test the latest upstream kernel? Refer to https://wiki.ubuntu.com/KernelMainlineBuilds . Please test the latest v3.18 kernel[0]. If this bug is fixed in the mainline kernel, please add the following tag 'kernel-fixed-upstream'. If the mainline kernel does not fix this bug, please add the tag: 'kernel-bug-exists-upstream'. If you are unable to test the mainline kernel, for example it will not boot, please add the tag: 'kernel-unable-to-test-upstream'. Once testing of the upstream kernel is complete, please mark this bug as Confirmed. Thanks in advance.
