[Bug 106671] Frequent lock ups for AMD RX 550 graphics card

So the current lockup could be due to an entirely different bug than in the lockups I have encountered for the direct use case.

Yeah, that looks like an RCU or other core kernel issue, not directly related to the graphics drivers (which as you say, aren't really being used in this case).

Does idle=nomwait on the kernel command line help for any of these issues, by any chance?

It's also worth making sure the motherboard BIOS is up to date.
