[Bug 1854789] Re: Hard lockup using 5.3.0.24.28 from proposed PPA on focal
OK, this (or at least some part of it) finally reproduced on an upstream kernel (5.4.19-050419-generic)! I've attached the journal from "[ cut here ]" onwards, with some minor redaction of VPN endpoints. ** Attachment added: "5.4.19-050419-generic.journal.txt" https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1854789/+attachment/5329526/+files/5.4.19-050419-generic.journal.txt ** Summary changed: - Hard lockup using 5.3.0.24.28 from proposed PPA on focal + Hard lockup using 5.3.0.24.28, 5.4.0-13, 5.4.19-050419 on focal -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1854789 Title: Hard lockup using 5.3.0.24.28, 5.4.0-13, 5.4.19-050419 on focal To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1854789/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
[Bug 1854789] Re: Hard lockup using 5.3.0.24.28 from proposed PPA on focal
I've been using the mainline kernel (5.4.5, specifically) for a few weeks with no instability; I switched back to the -proposed kernel ~a week ago and I've since seen this issue recur. The version I saw this recur on was 5.4.0-13-generic (and I'm now on -14 as a result of the forced reboot). Is there anything more I can do to assist in addressing this issue? -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1854789 Title: Hard lockup using 5.3.0.24.28 from proposed PPA on focal To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1854789/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs

Thanks for looking at the bug! Which mainline kernel should I look to use? Is https://kernel.ubuntu.com/~kernel-ppa/mainline/v5.4.1/ the right one? -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1854789 Title: Hard lockup using 5.3.0.24.28 from proposed PPA on focal To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1854789/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs

RCU bug? I guess the best approach is to reproduce it on mainline kernel and raise the issue to RCU mailing list. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1854789 Title: Hard lockup using 5.3.0.24.28 from proposed PPA on focal To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1854789/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
