[SOLVED] Latest kernels won't boot.

Neljor · 07-09-2021, 11:17 AM

Dear people,
Having problems with the latest kernel kernel-default-5.13.0-5.1.g9140415.x86_64.
The later kernel kernel-default-5.13.1-1.1.gbebf622.x86_64 has the same issue.
But the kernel-default-5.13.0-4.1.gaa40472.x86_64 works fine, although for some reason logrotate fails to start at boot time en needs to be started manually.

The attachment shows the error I get when one of those two mentioned kernels are booted.

Code:

No kernel error. Looks like the kernel is up and mounting filesystems. systemd got the error that you see. I'd suggest backing up to the previous kernel and updating userspace.

Thank you.
Yes, but it only happens with the new kernel, so something is not compatible with the new kernel?
Also, root directory was not mounted in rw mode ad the faulty kernel immediately starts with not taking the configured resolution.

And how can I update userspace?

I'm not sold on the kernel but could be. See Kernel.org for the diff.

I'd boot to the working kernel and zypper it being sure use dup maybe first. My thought is either bad upstream issue or some reason it didn't fully update and reboot. Maybe a user issue. Plenty of ways to go on this but start with utmp.

Thank you all for your response or reading!

Booted one of the faulty kernels, and it starts immediately with not taking the configured resolution, starts with big letters.
Fails root partition to mount in rw mode, but can save it to the home directory.

Errors start at line 649

#journalctl -xb

Thank you kindly for your help.

Would believe there is some incompatibility with the latest kernels, but how or what (??), could try a vanilla one from kernel.org
openSUSE kernels have lots of patches. I don't understand anything about C programming, so checking the diff makes no sense for
me in understanding how it would impact the system.

Save for now, because the older kernels work fine.
Anybody tried the latest kernels?

Kindly,

Peter

Note that 5.13 is bleeding edge kernels: Even Fedora is still only in testing with those and only distributing the 5.12 kernels so far. Maybe it would be wise to be a little slower in moving to the latest.

Thanks, just installed the kernel-default-5.12.15-lp152.1.1.x86_64 kernel, see if this is good enough for the external soundcard.

Also replace the old kernel.repo with a new one that does not have the 5.13 kernel.

Have a great day!
