The details+logs are here (previous e-mail did not go through, too large for the list): wget http://home.comcast.net/~jpiszcz/20091014/nut-problem.txt
For now I have disabled nut-- is there any more debugging that I can do to help find/solve the problem? Also cc'ing linux-usb & linux-kernel on this one.
Highlights from the above txt file:

The same cable, UPS etc was used on another motherboard for 1-2+ years without any issue, after moving it to a DP55KG, this problem began.
