Recently (last week) I was running 5.13.0-39-generic without problems.
After an update from Canonical the system became unstable, freezing
during boot, or freezing while running a normal app - basically
unusable. Looking at the GRUB menus I notice that the default version of
Ubuntu I was now running was 5.13.0-40-generic. Looking through the logs
I found in kern.log the following kernel Oops (see below at Apr 25
10:52:24 gamer kernel: [ 2.844018]).
This does not happen with the -39 kernel. It also does not happen if I
disable my Bluetooth/wifi hardware on the motherboard in the BIOS. I am
now running the -40 kernel with Bluetooth/wifi disabled.
I have included some context before and after.
