amdgpu: MES ring buffer is full issue.

I meet this issue several times recently

I am using a 7840hs (iGPU 780M) mini PC with 64G memory, and I set 16GB as the graphics memory

6.11.4-x64v2-xanmod1-1
GNOME + wayland

when this issue happen, system is hung frequently, and mouse/keyboard  lose response occasionally, 

i can saw GPU usage keeping 99% when i run nvtop, but graphics memory only use 3GB.

I started two local models use ollama, and start up a VirutalBox with Win11. but, after i disable all of them,
still very lag, even,  kill -9 on wezterm no any response, i try to click reboot button on GNOME desktop failed.

the only i can do is, Alt + REISUB, and wait 30 seconds, it reboot successful.

Can i know what's causing this issue usually? OOM on graphics memory? or others issue?

Thanks.
