[Soekris] OpenBSD 4.0 boot hangs on net4801 with lan1641

[Jules Colding]

Hi,

I've just successfully installed OpenBSD 4.0 on a net4801-60 with a
lan1641 Ethernet PCI board and a SAN Extreme III 2GB CF. 

The installation completed flawlessly after I disabled pciide at the UKC
prompt. The problem is now that I'm trying to boot the net4801 but the
boot always hangs with:

I've tried two different CF cards (both the same kind of SAN card) but
to no avail. They both hang at the same place during boot.

Any clues?

Thanks a lot in advance,
