[Bug 1204952] New: System crashes when booting first time after kernel update
http://bugzilla.opensuse.org/show_bug.cgi?id=1204952 Bug ID: 1204952 Summary: System crashes when booting first time after kernel update Classification: openSUSE Product: openSUSE Distribution Version: Leap 15.4 Hardware: x86-64 OS: Other Status: NEW Severity: Major Priority: P5 - None Component: Kernel Assignee: kernel-bugs@opensuse.org Reporter: Ulrich.Windl@rz.uni-regensburg.de QA Contact: qa-bugs@suse.de Found By: --- Blocker: --- I think I had observed this for the last three (or so) kernel updates: When the system boots the new kernel after a kernel update, the system reboots unexpectedly about at the moment when the filesystems were all mounted. Unfortunately there is no trace in journal or messages of that failed boot. However "last" seems to record those. I have: reboot system boot 5.14.21-150400.2 Wed Nov 2 09:21 still running reboot system boot 5.14.21-150400.2 Wed Nov 2 09:20 - 09:20 (00:00) reboot system boot 5.14.21-150400.2 Tue Oct 18 07:59 - 09:19 (15+02:19) reboot system boot 5.14.21-150400.2 Tue Oct 18 07:56 - 07:57 (00:00) reboot system boot 5.14.21-150400.2 Fri Sep 23 12:07 - 13:00 (7+00:53) reboot system boot 5.14.21-150400.2 Fri Sep 23 12:05 - 12:05 (00:00) reboot system boot 5.14.21-150400.2 Thu Sep 15 12:08 - 12:04 (7+23:55) reboot system boot 5.14.21-150400.2 Thu Sep 15 12:07 - 12:07 (00:00) reboot system boot 5.14.21-150400.2 Tue Aug 16 08:55 - 11:57 (30+03:01) reboot system boot 5.14.21-150400.2 Tue Aug 16 08:46 - 08:54 (00:07) reboot system boot 5.14.21-150400.2 Thu Jul 28 07:43 - 08:22 (19+00:38) reboot system boot 5.14.21-150400.2 Sun Jul 24 16:31 - 23:07 (3+06:36) reboot system boot 5.14.21-150400.2 Sun Jul 24 16:20 - 16:30 (00:09) reboot system boot 5.14.21-150400.2 Fri Jul 22 23:39 - 16:19 (1+16:39) reboot system boot 5.14.21-150400.2 Mon Jul 18 14:38 - 14:58 (4+00:19) reboot system boot 5.14.21-150400.2 Thu Jul 14 12:07 - 10:09 (3+22:02) You see that starting around August 16th, there are two boots within rather short time (a boot here takes some time as I have to enter passwords for encrypted filesystems three times, and GRUB's decryption is rather slow, too). You also see that the new kernel version strings are not quite compatible with "last" (they are too long). -- You are receiving this mail because: You are the assignee for the bug.

Unfortunately kdump wasn't installed by default. Also I wonder why the kernel would have a problem exactly when started for the first time. -- You are receiving this mail because: You are the assignee for the bug.
