Hi Martijn,

That is rather worrying. The kernel in buster is 4.19.67-2+deb10u2.
In the previous release (stretch) it is 4.9.210-1 and in the one
before that (jessie) there was 3.16.81-1.

That's absolutely ancient and I am amazed that your system works at
all.

Any ideas how you have managed to end up running a Debian 6
(squeeze) era kernel on a Debian 10 user land?

That kernel went end of life for security updates in 2014 by the
way!

Are you sure you're actually running Debian stable, i.e. you have
previously done an "apt-get update" and then an "apt-get
dist-upgrade" which all completed okay in the past?

What kernels do you actually have installed right now?

$ dpkg -l | grep linux-image

What is the output of:

$ ls -la /boot/

What happens when you update your grub config:

$ sudo update-grub

I would really hope that it is just a case of there being an old
kernel hanging around that your boot loader keeps selecting but
honestly this is so weird that I would not trust your system to come
back up correctly if you rebooted it right now.

Cheers,
Andy
