I keep getting random kernel panics throughout the day that seems to be related to the Intel Kaby Lake driver triggering a page fault. Is this a known issue? These do not occur on Catalina (I dual-boot)

panic(cpu 2 caller 0xffffff800dfee996): Kernel trap at 0xffffff7facfb74e4, type 14=page fault, registers:

I have the exact same issue/error. Seems to happen randomly at least once I day. I also experience this issue in Catalina although it wasn't as frequent. Seem some comments speculating its tied to an issue with the logic boards in some of the 16" MBPs? But nothing definite that I've seen or been able to find
