>Description:
I run a two FreeBSD boxes each with two SuperMicro AOC-SAT2-MV8 SATA
controllers providing 8 SATA ports per card. Based on the Marvell
Hercules 2 chipset, this is a nice setup for a ZFS fileserver. See
http://www.supermicro.com/products/accessories/addon/AoC-SAT2-MV8.cfm
for further Information regarding card and chipset.

Unfortunately since 6.3 or so, FreeBSD comes with the hptrr binary
blob driver from Highpoint. If the hptrr driver is present in the
kernel, it breaks detection of the SuperMicro AOC-SAT2-MV8 controllers.
(which normally are handled by the ata driver). Since the hptrr
driver is present in the GENERIC kernel, it is impossible to install
FreeBSD on a machine where all disks reside on the AOC-SAT2-MV8
controlers.

Since it is impossible to deactivate the hptrr driver during boot,
one needs to build a custom kernel without hptrr compiled in and
add hptrr_load="NO" to loader conf to install FreeBSD.

Both machined ar NOT equipped with any HighPoint hardware.

>How-To-Repeat:
Boot a 7.2 install disk on a machine equipped an AOC-SAT2-MV8 card:
no AOC-SAT2-MV8 controller detected. Remove hptrr as described above:
AOC-SAT2-MV8 controller detected.

I observed this issue on to machines:

(no Marvell card inside currently but with one the issue happens)

>Fix:
At least provide an option to disable htprr during boot time.
