We use SuperMicro twin servers with their AOC-SIMSO+ server remote
management boards, and our problems are very similar, if not the same,
as yours...

Same here. I tried pretty much all FreeBSD  live CD images I could find,
including a 9-current snapshot, same result. The kernel loads fine,
initializes, but fails to mount the root filesystem off the virtual USB
drive no matter what type I chose in the FixIt menu, or with FreSBIE at
the point where it tries to mount the root.

Actually, what I tried to achieve here is simply to boot into a live
image, so I could clone another system over the network. I also tried
an OpenBSD and a NetBSD live image the same way, both (!) booted fine,
but didn't have a raid driver for our adaptec controllers in those
images, so they were no alternative for my purposes.

I hadn't tried that approach yet, so I inserted an iso image into the
virtual usb drive:

Let me know if and how I can help in some way to debug this problem. 

We have another issue with this KVM board: on one system (there's about
20 identical servers, just one with this problem) we have keyboard/mouse
access over IP as long as IO is done via the BIOS (i.e. I can get into
BIOS menus, RAID controller menu, FreeBSD loader). However, as soon as
the FreeBSD kernel takes over and IO should be handled by the FreeBSD
USB stack, I see this error in dmesg:

uhub3: port 6, set config at addr 2 failed
uhub3: device problem (IOERROR), disabling port 6

it could be a faulti KVM board, but then I ask myself why access works
fine as long as BIOS IO is used..

Kind regards,
Markus
