Dmesg of NetBSD-4.0_RC4 is appended.

I can start FreeBSD 7-BETA3 if I disable the LAN in the BIOS and boot without 
ACPI as explained here:

http://www.nabble.com/RELENG_7-and-HEAD:-bge-causes-system-hang-t4804426.html

I tried the same with DragonFly, but that didn't helped.

I can, but it doesn't help much. I tried "unset acpi_load", but that gives the 
same result (panic). Maybe a SATA problem I thought? But I disabled "native SATA 
mode" in BIOS, so I guess it's now seen by DF as a (P)ATA controller.

Well, I just wanted to share this, maybe this will help others. For now I don't 
want to install DF anyway, because of lack of Bluetooth and wpi (and probably 
X3100 graphics support).

Thanks!
