misko, the next step is to fully commit bisect from kernel 4.4 to 4.8 in order to identify the last good kernel commit, followed immediately by the first bad one. This will allow for a more expedited analysis of the root cause of your issue. Could you please do this following https://wiki.ubuntu.com/Kernel/KernelBisection ? Please note, finding adjacent kernel versions is not fully commit bisecting. Also, the kernel release names are irrelevant for the purposes of bisecting. It is most helpful that after the fix commit (not kernel version) has been identified, you then mark this report Status Confirmed. Thank you for your help. ** Tags removed: kernel-bug-exists-upstream-4.9-rc8 ** Tags added: kernel-bug-exists-upstream kernel-bug-exists-upstream-4.9 needs-bisect -- 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/1647048 Title: System freezes after login (NMI watchdog: BUG: soft lockup - CPU#0 stuck for 22s) Status in linux package in Ubuntu: Incomplete Bug description: Since I updated to kubuntu 16.10 I quite often have the situation that my laptop completely freezes after login in sddm (that means: while KDE is loading).

What can I else do to find out what the kernel is doing while my computer does not respond? (can I turn the kernel or at least some of its modules to more verbose logging?) btw: what does the "rubbish" in the kern.log mean? Does it indicate an error in the filesystem or SSD driver? (or does it just mean that the meachine got unresponsive in the middle of writing to the disk?) -- 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/1647048 Title: System freezes after login (NMI watchdog: BUG: soft lockup - CPU#0 stuck for 22s) Status in linux package in Ubuntu: Confirmed Bug description: Hi, Since I updated to kubuntu 16.10 I quite often have the situation that my laptop completely freezes after login in sddm (that means: while KDE is loading).

Would it be possible for you to test the latest upstream kernel? Refer to https://wiki.ubuntu.com/KernelMainlineBuilds . Please test the latest v4.9 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.
