OK, this one baffled me for a while! You're quite right, in the very first dmesg I got (which is the one I sent in my first email): ucc0 at uhidev1 reportid 1: 4 usages, 3 keys, enum wskbd1 at ucc0 mux 1 but I have a record of several subsequent dmesg's and not one of them contains ucc -- even if I boot with the same snapshot kernel (#658). It turns out that's because my first dmesg was recorded while attached to an external keyboard (via a hub) and all the subsequent ones without an external keyboard. Here's wsconsctl if I boot without the external keyboard attached: $ doas wsconsctl | grep "^keyboard" wsconsctl: Use explicit arg to view keyboard.map. keyboard.type=pc-xt keyboard.bell.pitch=400 keyboard.bell.period=100 keyboard.bell.volume=50 keyboard.bell.pitch.default=400 keyboard.bell.period.default=100 keyboard.bell.volume.default=50 keyboard.repeat.del1=400 keyboard.repeat.deln=100 keyboard.repeat.del1.default=400 keyboard.repeat.deln.default=100 keyboard.ledstate=0 keyboard.encoding=unknown_0 And when I attach the external keyboard this becomes: $ doas wsconsctl | grep "^keyboard" keyboard.type=pc-xt keyboard.bell.pitch=400 keyboard.bell.period=100 keyboard.bell.volume=50 keyboard.bell.pitch.default=400 keyboard.bell.period.default=100 keyboard.bell.volume.default=50 keyboard.repeat.del1=400 keyboard.repeat.deln=100 keyboard.repeat.del1.default=400 keyboard.repeat.deln.default=100 keyboard.ledstate=0 keyboard.encoding=uk keyboard1.type=usb keyboard1.bell.pitch=400 keyboard1.bell.period=100 keyboard1.bell.volume=50 keyboard1.bell.pitch.default=400 keyboard1.bell.period.default=100 keyboard1.bell.volume.default=50 keyboard1.repeat.del1=400 keyboard1.repeat.deln=100 keyboard1.repeat.del1.default=400 keyboard1.repeat.deln.default=100 keyboard1.ledstate=0 keyboard1.encoding=uk keyboard2.type=usb keyboard2.bell.pitch=400 keyboard2.bell.period=100 keyboard2.bell.volume=50 keyboard2.bell.pitch.default=400 keyboard2.bell.period.default=100 keyboard2.bell.volume.default=50 keyboard2.repeat.del1=400 keyboard2.repeat.deln=100 keyboard2.repeat.del1.default=400 keyboard2.repeat.deln.default=100 keyboard2.ledstate=0 keyboard2.encoding=us.noencoding keyboard3.type=usb keyboard3.bell.pitch=400 keyboard3.bell.period=100 keyboard3.bell.volume=50 keyboard3.bell.pitch.default=400 keyboard3.bell.period.default=100 keyboard3.bell.volume.default=50 keyboard3.repeat.del1=400 keyboard3.repeat.deln=100 keyboard3.repeat.del1.default=400 keyboard3.repeat.deln.default=100 keyboard3.ledstate=0 keyboard3.encoding=uk Note that after the external keyboard attaches keyboard.encoding has changed from unknown_0 to uk; if I unplug the external keyboard the encoding goes back to unknown_0. I did a bit more digging and I've confused myself considerably, possibly because I don't know how wscons works. If I boot the machine without the external keyboard attached, stay in the console (i.e. outside X), and then plug in the external keyboard causes the laptop keyboard behaves bizarrely: for example "1" and "a" are inverted (i.e. I press "1" and "a" is displayed). After I unplug the external keyboard, I seem to get a new (more bizarre) map in the console where "a" is some sort of control code. I eventually managed to trigger a panic in wskbd_translate by doing this: https://postimg.cc/JtrN1GWy Note this happened with the stock #658 kernel (i.e. without Miod's patch). I suppose this isn't a very interesting panic in the sense that something has gone wrong quite before this panic occurred, but still, it might be useful info for someone! Laurie
