Hi Danny,
i made some tests with FreeBSD 7.0 Prerelease in december and the problem
is no longer present.
The crash and seg fault you see seems to be related to ACPI/SMP implementation
of freebsd6.
The problem is also present and more evident with VMWare virtual hardware.
No problems if you are using Intel hardware.
Hope this helps.
Daniel
