i915 0000:00:02.0: [drm] GPU HANG: ecode 12:1:859ffffb, in gnome-shell

I get constant GPU HANGS which render de computer unusable. The only solution I have found is to boot with the nomodeset flag, but this prevents the HDMI port from working. I'm using Ubuntu 21.10 Kernel 5.16.0rc6 (same problem with all other pervious kernels)
