It seems the Stop 0×9F Error is back in the Firewire Solo Windows 7 beta driver. As in previous versions of windows, this error occurs when your computer
wakes up from sleep mode or when one or more
drivers installed on your computer are unable to handle power state.
The error was described in previous windows versions here:

The vista fix was posted here(but I've yet to find anything for Windows 7...and from my limited understanding these fixes are not needed if the drivers are written correctly):
