Boot time seems unreasonably long

Hello everyone,

I have quite long boot time considering I installed Garuda on a NVME drive (512GB) on a Dell XPS 13 laptop. SecureBoot is disabled as well as fast boot. The drive is encrypted with LUKS. (Un-Encrypting that takes long, too. Don't know if that's the same or another issue.)

As you can see the longest time is in the 'loader' (That's probably the part where the circle is spinning because it takes really long.)

Note that I'm running the linux-lts kernel because linux-zen had issues with some system hangs.

Thanks for your help.

Edit: Just tried pressing F12 during Boot:

I had following messages appear:
Failed to open key file.
ERROR: resume: hibernation device '/dev/mapper/luks-...' not found.

So maybe LUKS is the problem?

I did a Google search on that phrase and it returned many hits. You need to do so, as well.
Anyway, I thought this was an interesting one: Btrfs Encrypted with small or big swap - partitioning automatically - error message · Issue #1659 · calamares/calamares · GitHub

In addition to the above, at a quick check on the Arch Wiki
https://wiki.archlinux.org/title/Dm-crypt/Encrypting_an_entire_system#Overview
I see #LVM on LUKS is the suggested scenario with " Easiest method to allow suspension to disk".
Just in case this info could be helpful (I'm no expert of this stuff)...

This will possibly reduce by 8 sec

But it would still more than 1 minute, which is quite irrational.

Post your /etc/fstab
(It is a text file and you have to copy paste its content here)

This is the boot loader, which is probably GRUB, and that has a known issue with slow decryption of encrypted boot partitions.

Also have a look at systemd-analyze critical-chain as this will tell you which services are actually impacting boot time (rather than just taking a long time to start).

NetworkManager-wait-online probably doesn't affect boot time to login.
