Kernel errors with drivers/gpu/drm/i915/intel_pm.c

Hello! I've recently been getting kernel panics and I seem to get the following errors every second when following journalctl:

Re: Kernel errors with drivers/gpu/drm/i915/intel_pm.c

I suggest you try without the ck patches. I have heard of these patches exposing some exotic bugs in the USB subsystem. I would not be surprised if it's the same case here.

I am getting those errors without the -ck patches and I am also using a Thinkpad T420
