Bug Description
Today one of my NUCs got new kernel 6.5.0-14 and the host started to hang few minutes after the boot.
I can't find anything in the journal for the previous boot it just ends without any error. Remote syslog server does not receive any error log from this host. I've tried running journalctl on the local console and wait for the hang got nothing.
On the screen (this is Ubuntu Server) I see 18 hex numbers at the top of the screen and the rest is what was on the console before the hang:
ff ff 73 01 c3 48 8b 0d 74 ed 12 00 f7 d8 64 89 01 48
Booting the previous HWE linux-image-
I don't have enough time to generate report with ubuntu-bug on the new kernel, so attaching dmidecode, lspci, lsusb and dmesg from the older one.

I was able to find one single line that syslog server was able to catch:
[ 353.589347] BUG: kernel NULL pointer dereference, address: 0000000000000008
I guess it doesn't give a lot of information...
