For whatever it's worth, I want to be clear that all stock kernels are 100% unusable on lenovo P17gen2 because of this deadlock and that without the temporary patch, my laptop would be usuable. It was also a risk of data loss due to repeated deadlocks and unclean shutdowns. I cannot say what the correct fix is, but I am definitely hoping you will accept some solution for the next stable kernel.
