Hi guys,
I have a bit of an unusual problem. My kernel updated recently, from 6.2.0-31 to 6.2.0-32 (I think), and the system will not fully boot up from the grub menu with the most recent kernel.
If I go to advanced options from the grub menu, then select the previous kernel, (6.2.0-31), it seems to work fine.
I cannot copy and paste, or take a screen shot, during the bootup process, but I do remember seeing something about kernel null pointer.
There was also something about processes involving userspace out-of-memory process killer, timy syncronization, and network name resolution not being completed.
After booting with the older kernel, I did perform the following commands:
Code:
systemctl status systemd-timesyncd.service
systemctl status systemd-oomd.service
systemctl status systemd-resolved.service
which gave the following output:
Code:

I noticed that the sofltlink with the .old suffix is pointing to the most recent kernel.
Not sure if that information helps or not.
My hardware is a Tecra dynabook intel core i7.
Thanks for any insights,
