Phoronix article: Coreboot Lands Support For The MSI PRO Z790-P Motherboards
On Dasharo (who worked on support for MSI boards) has pre-flashed motherboard for sale on their website, but looking at the price it's expensive, but it comes with some support.
On my system there is no traditional log files like kern.log or message (Not sure about Ubuntu 22.04), I would say it's worth a try.
Try journalctl --boot -1 -xe or journalctl --boot -1 -xep3
Lubuntu
When I started playing Horizon zero dawn, for first dozen hours I was in the state that fears the machines and sneaks everywhere.
Aloy's voice still terrifies me, I wish there was an option to turn off her random monologues.
The problem has been solved, it's caused by mesa's video decoding package, I will answer anyway.
Yes, VCN (Video Core Next) column stays at constant value while playing video (3% for VA-API with mesa, 5% for VDPAU with mesa, 0% for libplacebo), GFX fluctuates between 0% and 1%.
Just playing a 1080P video (not even a high bit rate one) is enough to make GPU fan go spinning, disappointing.
Turns out in my case it's mesa driver causing my problem, after removing mesa's VA-API and VDPAU drivers VLC can still play things just fine, CPU is at 2~3%.
Through some more testing, I found out mesa related hardware acceleration package can cause these power surge, on Archlinux it includes mesa-vdpau and libva-mesa-driver.
If I don't have these package installed, VLC reverts to libplacebo which doesn't seem to cause more power usage.
do you also have a dedicated graphics card?
Yes, rx 7800 xt
My worry s that playing a 1080P video need 30 watts (assuming amdgpu_top is not wrong), I would like to move that workload to integrated GPU, which I enabled in BIOS.
Thank you for your answer, I can confirm by switching to VA-API it lowers my power usage by a lot (from 45 to 20~21 watts reported).
Yes, rx 7800 xt. I can confirm DRI_PRIME does switch to integrated GPU on demand
DRI_PRIME=0 glxinfo | grep "OpenGL renderer"
OpenGL renderer string: AMD Radeon Graphics (gfx1101, LLVM 16.0.6, DRM 3.54, 6.5.5-arch1-1)
DRI_PRIME=1 glxinfo | grep "OpenGL renderer"
OpenGL renderer string: AMD Radeon Graphics (raphael_mendocino, LLVM 16.0.6, DRM 3.54, 6.5.5-arch1-1)
Isn't that the same as yay?
When source code is lost or unavailable.
There is a "point" in ender dragon's hitbox, when player gets close to it gives the player very high velocity, by shooting an arrow before player gets damaged and go flying, the velocity is transferred to the arrow, one shot the ender dragon.

AFAIK LET do shenanigans like requiring service providers to pay to create post there now.
