5.19 dmesg with warning, GVT-g doesn't work

I'm using Intel GVT-g actively and it was very stable on older kernels
including 5.18.x.

But after updating to 5.19 it doesn't work anymore. I'm sure that it isn't
related to hardware change / bios update. It still works if I reboot to older
5.18 kernel. 


I'm getting followed in dmesg:

[   92.987534] ------------[ cut here ]------------
