The migration is almost done, at least the rest should happen in the background. There are still a few technical difference between the old cluster and the new ones, and they are summarized in this issue. Please pay attention to the TL:DR at the end of the comment.

System unresponsive/very slow when booting with 2 monitors on 7900XTX

Since variable refresh rate was turned on by default in kernel 6.5, my system becomes terribly slow and unresponsive when booting into the Display Manager (SDDM) - I'm not able to switch to a terminal and am forced to hard-reset my computer.

This issue seems to only happen when I only have 2 monitors plugged in on boot.

I can work around the issue if I leave at least 1 monitor unplugged when the system boots into SDDM, and reconnecting it once I've booting into my DE (KDE). I suspect this might be happening due to only 1 of my 2 monitors supporting VRR (the other only supports G-Sync).

Hardware description:

CPU: AMD Ryzen 7950X3D
GPU: Sapphire Pulse RX 7900XTX
System Memory: 64GB
Display(s): LG 34GP950G (supports freesync/VRR), Asus ROG PG279Q (only supports GSync)
Type of Display Connection: DP (both)

System information:

Distro name and Version: EndeavorOS/Arch Linux
Kernel version: 6.5.9-arch2-1
Custom kernel: N/A
AMD official driver version: N/A

How to reproduce the issue:

PC is turned off with both monitors plugged in
Boot normally
System becomes unresponsive/terribly slow when Display Manager (SDDM) starts

This might be related to #2870

Booting with two monitors on 7000 series does cause a crash.

This definitely seems related. Your log show the same stack trace as what I posted here.
