Upgraded kernel => system stuck on "Reached target graphical interface

So I upgraded the system, including the kernel from 5.8.10 to 5.9.4 from the pacman repo. The following boot the system is stuck after "[ok] Reached target graphical interface", leading to a black screen. Can't switch ttys, can't do anything, but no panic.

Starting with i915.modeset=0, no change ("reached target graphical interface stays on").

However, starting with the kernel parameter "systemd.unit=multi-user.target" allows me to manually start lightdm/xorg and everything works fine.

This is a kaby lake (7200u) laptop, with intel+amd gpus. The window manager is xmonad (not that it matters).
Downgrading fixes the issue again.

Has anyone run into this issue? Xorg logs, journalctl or dmesg doesn't show any significant differences between the two kernels.
Thanks.

Re: Upgraded kernel => system stuck on "Reached target graphical interface

Same problem on 5.9.6. I guess I should compile the kernel from source and diff between the two versions (after bsearching between 5.8.10 and 5.9.4). But that's a lot of work. I'll stay on 5.8 in the hopes the issue will get fixed in the future.

That suggest you're facing the  - slowly getting infamous - race condition where graphical target is reached before the videocard / driver have finished initialising.
Try configuring Early KMS .
