>Description:
Try to install 9.0-RELEASE amd64 on HP DL365 G5
Kernel is loading until usb2.0, then freezes.
This effect is discussed at

http://osdir.com/ml/freebsd-hardware/2012-03/msg00008.html

since March 2012

it seems to me that the machine tries to mount usbus devices for root

under 8.3-RELEASE these are identified correctly as

usbus0: 12Mbps Full Speed USB v1.0
usbus1: 12Mbps Full Speed USB v1.0
usbus2: 12Mbps Full Speed USB v1.0
usbus3: 480Mbps High Speed USB v2.0

>How-To-Repeat:
Try install 9.0-RELEASE amd64 on HP DL365 G5
