[Bug 2136978] Re: grub2-common.service fails to load after cold reboot

2026-01-05 Thread Stefan Bader 
The relevant error seems to be "grub-editenv: error: invalid environment
block" which both units emit when failing (grub-common.service and grub-
initrd-fallback.service). In both cases grub-editenv is called to modify
the content of /boot/grub/grubenv.

I suspect something sets values shortly before reboot and reaching those
targets is supposed to unset them to indicate a successful boot. I am
not sure how much the kernel is directly having an impact here. Other
than maybe a different behavior on flushing pending writes on a
filesystem... In the end it seems the grubenv file gets corrupted. It
would be interesting to know whether after failing the following command
still shows issues: "grub-editenv /boot/grub/grubenv list".
