Hi

OpenBSD stock kernel might not be able to boot in most of newer HP
laptops. My pavilion also fails to boot because OpenBSD kernel does not
have ACPI CMOS RTC handler.

Can you try booting kernel with ec disabled? You don't have to disable
it in laptop's bios just configure kernel before booting.

To have better idea of what is actually causing the problem you can
compile kernel with #define ACPI_DEBUG and boot with it. If it's indeed
hp ACPI CMOS issue it will fail with message : Unsupported region space
5 when kernel crashes.

I have a wip patch based on linux's implementation but it's too
invasive and hacky right now for sharing. As soon as I get more time
I'll open up discussion in tech@ after tidying things up.

There was discussion on FreeBSD bugs lists of how to handle hp laptop's
acpi cmos some time ago but developers could not agree on resolution.
