Ubuntu 22.04 taking 3 minutes to load kernel

After upgrading from 20.04, the boot process now takes minutes more than before.

I'm using kernel 5.19.0-051900rc6-generic and Ubuntu 22.04.3.

Log from systemd-analyze:

Startup finished in 4.675s (firmware) + 3.850s (loader) + 3min 2.684s (kernel) + 13.403s (userspace) = 3min 24.613s 
graphical.target reached after 13.348s in userspace

Link to the 'before splash' screen:

Part of dmesg (can't understand the gap):

I already tried to uncomment these lines in /etc/systemd/system.conf while altering the timeouts to like 10s, but nothing changed:

#DefaultTimeoutStartSec=90s
#DefaultTimeoutStopSec=90s

Another issue I had these days is that linker can't find -lpangox-1.0, when building a c++ application using flycapture and ogre. So it may be related to some sort of graphics issue. (obs. the lib is actually already installed)

Edit: Solved after doing a fresh-install...

Most people don’t grasp that asking a lot of questions unlocks learning and improves interpersonal bonding. In Alison’s studies, for example, though people could accurately recall how many questions had been asked in their conversations, they didn’t intuit the link between questions and liking. Across four studies, in which participants were engaged in conversations themselves or read transcripts of others’ conversations, people tended not to realize that question asking would influence—or had influenced—the level of amity between the conversationalists.
