Anybody on this, pleeeease? :)

Am I missing something basilar, or it's a FreeBSD bug?
Incomplete support for the ICH9R?

I cannot attach the boot log, because the boot process
panics just before mounting the disks and nothing is
logged on /var/log/

Anyways, booting in verbose mode shows that the last
activities before it panics are on the disks and fakeraid..
it finds one of the disks and then the last output before
the panic is about the Intel MatrixRAID.

Any thoughts on this, please?

Best regards
