There's an one hour test with Lenovo ThinkCentre M910Q in pair with MESA 7i96S. System has nVme-disk so even Sata-bus is disabled. All normal shenanigans in Bios are made. I also add the isolcpus=2,3 in Grub config.
I changed script a bit to show some Unreal Engine 5 demovideo and do some internet search during the test.
