[Kernel-packages] [Bug 1585081] Re: Switching user freezes system
DavidEG, the next step is to fully reverse commit bisect from kernel 4.4 to 4.6 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 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. After the fix commit (not kernel version) has been identified, then please mark this report Status Confirmed. Thank you for your understanding.

[Kernel-packages] [Bug 1585081] Re: Switching user freezes system
Since I've upgraded to 16.04 I've started to experience these system crashes: * Sometimes, when I plug/unplug an external hdmi monitor. * Sometimes, when I shutdown the machine. Haven't reported those as they happen a bit randomly. I am not able to reproduce them at my will. The one reported here, happens always. Before upgrading to 16.04 I only had one user so I don't know if the problem was there. That said, my feeling is that it is caused by the upgrade because the aforementioned issues. Tested with the upstream kernel. The issue disappears (4.6.0-040600-generic #201605151930). ** Changed in: linux (Ubuntu) Status: Incomplete => Confirmed -- You received this bug notification because you are a member of Kernel Packages, which is subscribed to linux in Ubuntu. https://bugs.launchpad.net/bugs/1585081 Title: Switching user freezes system Status in linux package in Ubuntu: Confirmed Bug description: Just doing this my system freezes: 1.

[Kernel-packages] [Bug 1585081] Re: Switching user freezes system
Did this issue start happening after an update/upgrade? Was there a prior kernel version where you were not having this particular problem? Would it be possible for you to test the latest upstream kernel? Refer to https://wiki.ubuntu.com/KernelMainlineBuilds . Please test the latest v4.6 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'. Once testing of the upstream kernel is complete, please mark this bug as "Confirmed". Thanks in advance.
