I think we might have a problem with this kernel on raspberry pi devices that have wifi. I noticed that the non-wifi devices like cm3 and rpi2 passed just fine, but for *every* device that has wifi (rpi4, rpi3, rpi400, cm4, etc), on both armhf and arm64, they all fail the bg, n, and ac wifi tests - but just when wpa is used, not for open APs.
That initially sounded more like an AP problem to me, so as a sanity test, I reverted the kernel snap to the one in stable (5.15.0-1030.32  r635) and it worked fine

As a second sanity test, I refreshed it again to the beta kernel,
configured wifi to connect to one of the wpa APs, confirmed it failed.
Then I reverted again to r635 without changing the config, and wifi
worked immediately.

The tests we run gather some output from journalctl, etc. I've pasted a redacted version just in case it's useful:
