| My last chance was booting bsd.sp, the single processor kernel.
| Sadly, that just reboots without any further output to the console:

| 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?
