This message shows you were running a snapshot with a known bug. The bug is not related to this message; this message is just a debug message which my code triggered by mistake. However, the diff which prints this message has the known bug and it was included in snapshots for a while. A better diff was posted here: http://marc.info/?l=openbsd-tech&m=146384048501213&q=raw Can you please try this? The bug was that data frames were not protected with RTS/CTS frames. For some reason the old iwm(4) firmware didn't seem to have a big issue with this, or we just didn't notice as much. The new firmware seems to cause interference as a result, which also affects other wifi devices. I suspect some APs decided to switch channels due to this interference, which in turn caused the connection to drop entirely because OpenBSD doesn't follow channel changes. I've observed this problem myself with the broken diff, but cannot reproduce it with the new diff. Perhaps that's not what really happened, but I don't have a better explanation. In any case, I'd really like to know if the new diff works better for you.
