Do you know if we are doing any validation on the SDP3430 or Zoom boards? 

Using defconfig for the SDP3430 the kernel failed to boot. I found that this was due to the MUSB driver and SmartReflex. Disabling these allows it to boot.

Off mode does not appear to be working currently on the SDP. It hangs when enabled. Is off-mode stable on any of the boards?

Is this what everyone is using or is there any other diagnostics available through the proc or sys file-systems? Powertop is fine but I am curious how people are validating which c-states are being entered.
