You sent it only 4 days ago! As you might have noticed you're not the
only one to request help, code reviews or anything that requires time
from only a few people. What progress have you made on your side on
the analysis of this problem in during this time, that you could share
to save precious time to those who are going to help you, and to make
your issue more interesting to analyse than other ones ?

Also, I'm seeing that your kernel is tainted by an out-of-tree module:

                                             ^^

Most likely it's this "xt_geoip" module but it may also be anything
else I have not spotted in your dump. Have you rechecked without it ?
While unlikely to be related, any out-of-tree code must be handled
with extreme care, as their impact on the rest of the kernel remains
mostly unknown, so they're the first ones to disable during
troubleshooting.

Please always mention the exact version in reports. I've seen "5.4.181+"
in your dump, which means 5.4.181 plus extra patches. Have you tried
again without them ?

Hoping this helps,
Willy
