As described here on my Librem13v4 with my kernel parameters the actual kernel doesn’t start.
Because of that I wanted to change the kernel used in “Default Boot” to the older one which I can select and start from the boot menu.
When I select the kernel in heads boot menu I get a selection whether I’d like to start the kernel or make it the default boot kernel.
When I select the latter I’m requested to provide my LibremKey to sign the change, I have to enter my PIN and after that heads starts immediately a kernel - the newest kernel that doesn’t work and hangs after kexec.
When I then reboot the broken kernel is still default kernel and I can’t “Default Boot”.
I uninstalled the broken kernel and by doing so could have the older kernel as my “Default Boot” kernel, but uninstalling the newest kernel uninstalls also the meta package needed for kernel updates.
Any suggestion how to change the kernel for “Default Boot”? If needed I could take pictures of the process…
