Hi,
I know, the Raspberry Pi Zero 2 is officially not supported by OpenBSD,
but in general, it runs fine with the correct dtb. The Pi Zero 2 is connected
to an Waveshare PoE Ethernet/USB hub, with an RTL8152B ethernet chip.
Usually after a day or two, OpenBSD 7.8 panics. These panics also
happened with OpenBSD 7.7.
Machine is just running a standard OpenBSD installation with ssh and
AdGuardHome, no other services are running.

After executing this, the Pi Zero 2 just hangs, no further output.
I’m also attaching dmesg here, as it shows an error on the ure0 interface
right before the panic:
