[BUG] udev high CPU usage and trouble shutting down on archlinux-zen-6.5.8

[BlackOutedMind]

Describe the bug
A clear and concise description of what the bug is.
After installing EnvyControl I rebooted into hybrid mode, but my system sat at the shutdown screen with the following text:
229.011736] systemd-shutdown[1): Waiting for process: 361 ((udev-worker)), 350 ((udeu-worker)), 318 ((udeu-worker)), 328 ((udev-worker)), 302 (systemd-udevd) 246.869244) INFO: task (udeu-uorker):318 blocked for more than 122 seconds. 6.5.8 zen1-1-zen 81 OE Ta inted: P ( 216.869514) [ 246.869780 ] "echo 0 > /proc/sys/kernel/hung_task_timeout_secs" disables this message.

To Reproduce
Steps to reproduce the behavior:

1. Run sudo envycontrol -s integrated
2. Reboot
3. After booting up system is fine, until after some time udev kicks in with a high CPU usage.

Hi, the same happens to me every time I reboot from integrated GPU mode.
I might also add that my Nvidia GPU is not turned off, even when in integrated mode. (GreenWithEnvy reports a somewhat stable 2W consumption)
Envycontrol version is 3.3.1 and reports integrated mode.

I have very low knowledge in the matter. I just stumbled on something that might be a fix.

TLDR: After having installed/updated the nvidia drivers from hybrid (or full nvidia ?) mode, reboot (might be unnecessary), switch to integrated mode, reboot, and reinstall acpi_call-dkms. Needs a forced shutdown after that install, but then things seem to work fine (nvidia gpu is off in integrated mode and shutdown goes through)

The rest of this comment describes my adventure with that. Not very scientific process tho.

---

The two problems (no shutdown, no power-down of dGPU in integrated mode) were fixed after installing acpi_call-dkms
it seems like sometimes the nvidia card is turned off, and sometimes not. The laptop has no problem shutting down when nvidia gpu is off.
The bug reappears sometimes (probably every times kernel modules are rebuilt, or nvidia is updated). I have limited data available, but reinstalling acpi_call-dkms (which rebuilds something for sure) fixed the bug after reboot

At one point I thought that it seemed to be nvidia-version specific:

I updated nvidia stuff today to version 550.76-2. I could not get greenwithenvy to work.
Other symptoms were (including, but not limited to):

• In hybrid mode, suspending then resuming would let me on the last rendered frame before the suspend with no way to directly interact with the computer
• in integrated mode, nvidia gpu is present and running, and I got the same problem than OP when trying to reboot
  I rolled back to the last version I had of nvidia stuff which was 550.67-1. After a reboot, things work again

But I updated my system today to nvidia 550.78-1 and after doing the tldr things work
