Unfortunately, this bug is not reproducible, I don't know how to induce it. And it happens occasionally. It happened one more time after initial bug report. So, twice in 10 days or so. I am willing to test the upstream kernel but I don't know how long would I need to wait for bug to re-appear. And, it will be very hard for me distinguish if the absence of the bug is due to: * bug fix, OR * bug waiting long to re-appear
As far as I remember, there was no system upgrade before the event. Again, I'm not so certain about it because it might have been introduced by an earlier update/upgrade and waited long to appear. -- 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/1802382 Title: [860399.181468] watchdog: BUG: soft lockup - CPU#4 stuck for 23s!
