I was quickly seeing that systemd-userdbd.service was failing at boot.

if I restart the service it works fine, once the system is fully booted
It seems a problem with kernel 6.6.7, if I boot with the older 6.1.38 it works fine But I am not sure about which new option is causing this :/
Latest working version is kernel 6.4.3... I didn't try 6.5 and I couldn't guess which newer option could involve some kind of hardening that could cause this issue
The same with 254.7
Could you report it upstream please?
(In reply to Sam James from comment #5) > Could you report it upstream please? Yep, I was waiting to see a bit the progress to not spam here too much. Finally they found the culprit, let's see if it can be included for 254.8 :D
