[Bug 1617632] Re: System entirely freezes--keyboard, mouse no use
Hi Eric, |As it happens, I just re-started testing new kernels yesterday and so far 4.8.0.32 seems to work, no hangs yet. (Reminder: this used to happen mostly before login but also sometimes after hours of working). I will keep on testing and you guys updated. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1617632 Title: System entirely freezes--keyboard, mouse no use To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux-lts-xenial/+bug/1617632/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs

With crashdump enabled, hopefully you could then get a vmcore under /var/crash that will provide more informations as of why the system hangs. ** Changed in: linux-lts-xenial (Ubuntu) Status: Confirmed => Incomplete -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1617632 Title: System entirely freezes--keyboard, mouse no use To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux-lts-xenial/+bug/1617632/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
[Bug 1617632] Re: System entirely freezes--keyboard, mouse no use
Hi Ante/Peter, Based on your previous comment, it seems like Ubuntu kernel v4.4 doesn't exhibit the hang but ubuntu kernel v4.8 does ? If it's the case, then can you reproduce the problematic with the same mainline kernel versions[1] ? If yes, then I recommend you to shorten to amount of commits by testing the mainline kernels between the two until you have shorten enough to start a kernel bisection[2] Assuming the hang doesn't collect any informations in /var/log/ nor provide a stacktrace when it hangs. You can also enable the crashdump mechanism[3] + enabling enabling via sysctl various types of panic conditions[4] for the kernel to panic immediately under these conditions. Example : kernel.hardlockup_panic = 1 kernel.hung_task_panic = 1 kernel.panic_on_io_nmi = 1 kernel.panic_on_oops = 1 kernel.panic_on_unrecovered_nmi = 1 kernel.panic_on_warn = 1 kernel.softlockup_panic = 1 kernel.unknown_nmi_panic = 1 vm.panic_on_oom = 1 [1] - http://kernel.ubuntu.com/~kernel-ppa/mainline/ [2] - https://wiki.ubuntu.com/Kernel/KernelBisection [3] - https://wiki.ubuntu.com/Kernel/CrashdumpRecipe [4] - https://www.kernel.org/doc/Documentation/sysctl/kernel.txt Hope it helps ! -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1617632 Title: System entirely freezes--keyboard, mouse no use To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux-lts-xenial/+bug/1617632/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs

I further tested startup options and found this does not happen until trying to use kernel 4.8.0-27. 4.8.0-26 seems to work fine so far. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1617632 Title: System entirely freezes--keyboard, mouse no use To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux-lts-xenial/+bug/1617632/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs

This same thing happens to me after upgrading to kernel 4.8.
