Ok. Thanks for spending the time to check this thoroughly. I have already made myself spend many hours debugging ghosts after test observations like this, many many times :-) So I've become careful about quickly drawing conclusions from observations like this. Wifi is complicated and as far as I know nobody is ever testing OpenBSD wifi patches in an RF-isolated lab. Many problem reports I receive (and many of those arrive in private email, unfortunately) boil down to "it doesn't work when the cafe downstairs fills up with laptops and phones at lunch time" or "it only becomes slow when two or more laptops are doing video calls at the same time". The problem is that sometimes there are bugs to fix or missing features to implement in situations like this, so I cannot just dismiss such reports outright. But dealing with them can take a huge amount of time. To be honest, I wouldn't consider your problem a blocking issue. I would first wait to see if the exact same issue pops up elsewhere after the patch lands in the tree. > I'll now reboot to your other patch, again, and start testing again. Great, thanks! I would be surprised if it was 100% related, but if it actually is then I'm certainly interested in trying to debug it.
