USB problems on Sun Ultra 40 Workstation

Hello all,

I recently built 7.0-CURRENT, but I seem to be having some USB 
problems.  My usb keyboard works fine when the machine turns on, but as 
FreeBSD boots my USB goes dead.   Here is what the logs say:

usb0: OHCI version 1.0, legacy support
usb0: SMM does not respond, resetting
usb0: <OHCI (generic) USB controller> on ohci0
usb0: USB revision 1.0
uhub0: <nVidia OHCI root hub, class 9/0, rev 1.00/1.00, addr 1> on usb0
usb0: port 0, set config at addr 1 failed
usb0: root hub problem, error=4
usb1: EHCI version 1.0
usb1: companion controller, 4 ports each: usb0
usb1: <NVIDIA nForce4 USB 2.0 controller> on ehci0
usb1: USB revision 2.0
uhub1: <nVidia EHCI root hub, class 9/0, rev 2.00/1.00, addr 1> on usb1
uhub1: 10 ports with 10 removable, self powered
uhub1: device problem (IOERROR), disabling port 7
(I can post the full log if it would help)

The kernel configuration is GENERIC with MAC and BREAK_TO_DEBUGGER 
enabled.  Here is a list of hardware in the machine:

Sun Ultra 40 Workstation
2 AMD Opteron Processor Model 254 (Single Core)
1-MB On-Chip L2 Cache per Core
4-GB (4 _at_ 1-GB DIMMS) Registered ECC Memory
1 250-GB 7200 RPM SATA Disk Drive
1 NVIDIA Quadro FX 1400 Midrange 3D Graphics Card (P/N: X7265A)
1 DVD Dual (DVD-ROM and CD-RW Combo)
2 10/100/1000 BaseT Ethernet Ports
8 USB Ports
2 IEEE 1394a Ports
2 PCI-Express x16 Slots
2 PCI-Express x4 Slots
2 Conventional PCI Slots (32-bit/33 MHz)

I have tried with USB legacy support both enabled and disabled (logs 
from when enabled).  USB did work correctly on 6.1-RELEASE.  Has anyone 
else seen this or have any suggestions?

Thanks!
