Old HP/Compaq DC7900 unable to boot with kernel past 6.1.0. Flashing num local and caps lock

I gave it a few weeks to see if a newer TW build would resolve it.

I currently have:


Installed, but only the oldest one will boot.

I read a bit online and it seems these are kernel panics, and many indicated hardware failures. I would believe hardware failures, but the old kernel works without issue.

Any advice would be appreciated.

Thank you.

Boot without quiet and with plymouth.enable=0 on the kernel command line, then you should see panic message on the screen. Post a photo of it.

fwiw: over the years this has occurred on Laptops and pc’s. it also happened this week on a HUAWEI 15D, which is less than 1 year old.
Doing a fast power on/off cycle usually overcomes this effect.

On is with the KMS small kernel and the other is with the default.

I added plymouth.enable=0 at the end of the linux line in grub and booted.

In both cases the machine just stops with the caps and scroll lock lights flashing.

Was this installation to a VM, or directly to a PC? If directly to a PC, you need kernel-default, not kernel-default-base. 6.1.0 base working sounds like a lucky fluke. Kernel-default-base includes only a skeleton set of drivers.

I installed it on the bare metal 6-8 years ago and it has just been updated via zypper ever since.

As far as I can tell, it has always been running on the kernel-default-base.

I installed the kernel-default and rebooted. It is up and running again.

Thank you for the suggestion! I would not have noticed that!
