Re: [REGRESSION] linux 6.6.18 and later fails to boot with "initramfs unpacking failed: invalid magic at start of compressed archive"

[Radek Podgorny <radek@xxxxxxxxxxx>]

it's systemd-boot. attaching bootctl output. now looking at it, it seems 
that while systemd (and systemd-boot) gets timely updates on my system 
(currently at 255.4), the stub (is this how it's called?) does not get 
updated automatically in the efi partition (still at version 244?).

i can try to update it. but i'll wait for your instructions since this 
may be some rare situation and we may use it for testing.

anyway, i'm compiling new kernel with your suggested changes right now 
so i'll let you know how it turned out, soon.

r.

p.s.: ha! nevermind, i just checked the other systems which boot fine 
and they also are on stub (?) 244 so it's probably not the cause.
