Weird problem: kernel bug at shutdown
by sombragris from LinuxQuestions.org on (#5AWDH)
Running current and vtown. Root fs is ext4 on an SSD.
When I initiate a shutdown, my system shuts itself down.
Now, in the brief time where the graphical console disappears and I see again the text console output, I can get a glimpse of something like : --- kernel BUG at xXXXX
Then some dump of some numbers
and then I managed to see that there is a segfault on umount.
I tried to see any log of it either on /var/log/messages, syslog, dmesg, but there's no trace of it.
Yet, I can get that crash every time I shut down my system, either in runlevel 4 or even runlevel 3.
Sometimes the shutdown seems to be dirty, because on next boot it seems like fsck has to restore journal.
I cannot give a complete log of this since there are no traces of it on any of the system logs.
This seems to happen after the upgrade to kernel 5.4.80.
Any idea on what could this be? Thanks in advance.
