Log of iwlwifi on 5.17

Recently I updated to the Fedora 36 beta, with the 5.17 kernel. Ever since, I've experienced excessive issues with my Intel AX200 wireless card. Every other aspect of my usage has remained the same (laptop and router both in the same location, same number of devices on the network, etc.)

Before updating to 5.17, I was able to perform latency-sensitive tasks such as playing online games and use VoIP applications without issue, with acceptable latency. After updating to 5.17 it is at the point where I cannot have an enjoyable match due to constant ping spikes, often to the point where the game will "stutter" or "lock up" every 10 seconds or say, with excessively high ping to go along with this. My VoIP applications have similar issues with calls often being interrupted or distorted.

I reverted to 5.16.16 and this has alleviated the issue for the time being. I've included journal output from both 5.17 and 5.16 and you can see there are several issues/errors which are not present on 5.16.

Below is all I get from the journal for iwlwifi under 5.16. I've included 5.17 output as an attachment.

I'm not a developer for this code, but considering mailing the maintainers about this. But before I do that a quick question: is the problem still happening with the latest kernel? Ideally try with the latest 5.18-rc kernel please.

Kyle, did you give 5.18 a try? Is this problem still present there?
