What version of NT are you running? In the NT box, is it a Microsoft-provided 1394 driver or an OEM driver? Some of the early (pre-Win98SE) 1394 stacks had trouble with devices that didn't enumerate properly. That could be what's happening, the LPS bit is set in your SelfID, but the Link isn't responding to ConfigROM reads. Hence, Windows is completely baffled and continues to hammer on the Linux box until it comes up.
