Hi all,
I just upgraded one of my machines to -current and was surprised that
it didn't come back after reboot. Here's what I found on the serial
console:

The operating system has halted.
Please press any key to reboot.
My last chance was booting bsd.sp, the single processor kernel.
Sadly, that just reboots without any further output to the console:
boot> boot bsd.sp
booting hd0a:bsd.sp: 6884272+2204680+256480+0+667648 [72+729768+484465]=0xab69e8

Uh>> OpenBSD/amd64 BOOT 3.33
boot>
(The '5,' and 'Uh' are output on the serial console when the machine
actually resets, they've always been there and have never been an
issue before)
As I can't get into the machine anymore, I have no way to extract a
complete (older) dmesg. It was running 6.0 just fine before this
though.
Should teach me to always keep an older kernel around for emergencies.
Any ideas?
