Hi,

as the subject says, the 4.0BETA2 INSTALL kernel on a CD made from 
an iso image from releng.NetBSD.org produced a panic:

As the last few lines referred to ACPI, I restarted the machine and
disabled ACPI:

It was a surprise for me that this brand new machine does not start if
ACPI is _enabled_. From what I read on the mailing lists, modern machines
do not work _without_ ACPI.

The hardware page [1] does not list LSI SAS 1068 adapters (vendor 0x1000
product 0x0054) as supported, is this still true?

Further research[2] shows that OpenBSD's mpi driver might be what's needed
here.
