Extremely slow boot time after upgrade

[fakeyspinach]

Hi all,
I wonder if someone can give me some clue on this.
So usually it took me <20 seconds to boot in Big Sur.
I've upgraded to Monterey today and suddenly after the upgrade it takes more than 2 minutes.

1. Observing with eyes it mostly hang around somewhere like launchd- doing boot task : boot-root
2. I've tried different Trim timeouts but this doesn't seems to change anything.

Any help would be much appreciated.

Could be incompatible kexts. When I used the IntelBluetoothInjector.kext it caused the boot time to be about 5 minutes and a bunch of other things became broken.

Your bluetooth might be causing it. Check this

Could also be the faulty TRIM implementation of Samsung NVMe SSDs.

"...faulty TRIM implementation" rather 'conflicting' TRIM implementation right? That said, I boot from a Samsung 980 and it's about 1 minute from picker to login screen in my case. No huge delays I can tell - though Monterey is a lot more chatty on verbose mode. A lot of messages.

I don’t know the exact issue, just that Samsung SSDs need 1-2 minutes to TRIM while other drives take 2-3 seconds.

Seem to have lucked out with my 980 then!
