Intel AX200 horribleness

Seems like multiple people are having issues with Intel AX200 cards on Linux. There's plenty of stuff about it on the Internet, but there doesn't seem to be any well documented overarching resource about the problem.


We classify the following symptoms:

Name Observations
stall5g 5GHz networks work for a while, but suddenly stall - no more packets can be sent/received until reconnect/powercycle.
ok Everything works fine.
