I came home today to find my network unresponsive, and I have managed to narrow the culprit down to my OpenBSD 4.3 firewall. I attempted to power cycle it, but now at boot time it hangs, and all I get is the basic banner message.

Using drive 0, partition 3.
probing: pc0 apm mem[639K 31M a20=on]
disk: hd0+
>> OpenBSD/i386 BOOT 2.10

The "boot> " prompt at the end automatically backspaces away after a few seconds. Is that by design? If not, what does it signify? I have to maintain this machine so rarely that I have forgotten what normal behavior looks like.

Normal behavior is that it should pause for a few seconds to allow you to manually enter boot options, then continue booting. boot> shouldn't backspace away. – Joe Internet Jul 26 '11 at 0:31

The problem wound up being a faulty keyboard. I switched out the keyboard and everything is working correctly again. I have no idea why that would fix it, but it did.
