All of a sudden, whenever I reboot my APU2 (this does not happen on my APU1) - it stops. OpenBSD reboots successfully, but as soon as it boots up (I can see the bios menu on the serial console) it just stops. I can not see the OpenBSD boot loader.
This started happening approx 2 weeks ago, so it might be that my hardware is failing. Or it might be a OpenBSD problem. Power cycling the device "fixes" the issue. As in, I can boot normally. No other problems, apparently. I've been running on snapshots (amd64) Normally I only reboot it when upgrading to a newer snapshot, and at first I suspected it was installboot that was causing it. Just now I tried upgrading it chose /not/ to run installboot. Still same problem, so installboot was just a red herring. What can I do to help investigate this futher?
