I recently made a fresh installation of Gentoo on my new laptop using Binhost, it is my first try.
Problem is that opening and loading the swap partion takes very long time (like 2 minutes) (not restoring from hibernate).

The swap is on 128GB (64GB ram times 2).

Before I reinstalled gentoo I hade a ordinary gentoo (non binhost) on the device and swap with the same size to just seconds to load (sadly gone now https://forums.gentoo.org/viewtopic-t-1167160-highlight-.html ) . I have dual boot with Debian as and Debian also just takes seconds to load the swap.

I use encrypted root and swap using btrfs in LUKS for root and swap in LUKS for swap. I use dracut to generate the initrd.

I have never experienced something like this before and have no clue on what it can be. I have recreated the swap from within Gentoo and tested without ever booting Debian on it but no success.

Is it timing out - or is the swap activated (try swapon and see if it's listed)

Is it slow running cryptsetup, or is it slow running swapon ? swapon doesn't "load" anything as far as I know, it just enables swapping.

Hmm, wait, are you on nvme ? Try tweaking the swapon options:

While investigating to answer your questions I identified the problem; the resume parameter was wrong. It was resume=<Actual disk UUID> but should be resume=UUID=<Actual disk UUID>. The delay was resume from hibernation that timed out.

Thanx for helping me out, I'd never stumbled on it unless working with your questions.
