OpenBSD 4.3 on HP NX6110

[mk]

Hello all,

I was trying to install OpenBSD 4.3 on my old laptop HP NX6110.
I was able to install the system successfully but just after the 
installation finished and I pressed key to boot the system for the first 
time it crashed during the boot process.

And it crashes even for single user mode, I'm just able to boot by bsd.rd.
I was trying to search forums if somebody had similar problems but it seems, 
this laptop should normally work with OpenBSD.
I cut out HW faults as just before OpenBSD installation I was running other 
operating system without any problem.

I repeated whole installation process as well but problem persisted.
Unfortunately I can not provide dmesg.boot or other log file as I'm not able 
to boot the system.

I will be very happy for any help.
Thanks a lot.

MK
