Hi there. Apologies — I just missed your previous email. I can confirm the problem still reproduces on 254.5-1. To be clear: my symptoms are that I have at this point collected the list of modules my system needs to run, and listed them in /etc/modules. If I remove, say, iwlwifi from them, I boot into a system that does not have iwlwifi loaded, and thus no wifi functionality, until I manually modprobe iwlwifi.
It was merely a guess that it couldn't find hwdb, based on those log lines — if they are not unusual, then that guess falls apart. I'm willing to do any further log collection or investigation required, but I would need instructions on how to do so. What exactly is responsible for autoloading kernel modules based on hardware? Maybe it would help if I gained familiarity with that code file?
