ACPI - shutdown on current kernel

[Riccardo Mottola]

Hi,

I updated to a curent OpenBSD snapshot, to get more advanced ACPI 
support my HP laptop (other thread about battery status).

What I noticed now is an annoying behaviour: "shutdown -hp now" doesn't 
poweroff my machine. It apparently kills all processes, the display goes 
blank, but the CPU is still running and stays so forever. I accidentally 
packed my laptop in the case and found it all hot half an hour later :)

The fact can be reproduced and was not accidental. I need to press the 
power-off key for a couple of seconds to poweroff the computer. 
Filseystems were synced cleanly, because I don't get a FSCK error at the 
next power-on.

I suppose this is a bug, how can I give more information? Perhaps it is 
possible to retrieve the last kernel messages printed on shutdown?
