Kernel oops after running for a day

[kdart]

I recently got AA (Mamba 3.9) running on this router. It works OK... but then I got the following and user space (any UI) starts failing to respond.

Here's another one. An "undefined instruction" is an unusual one.

It does seem to be related to wifi. If I take my phone off of the wifi it doesn't crash.
