Default V2P7 Partial reconfiguration, FATAL_ERROR in par

Hi *,

I'm trying to do a module-based partial reconfiguration flow on a
Virtex2Pro (xc2vp7) according to xapp290 (I'm using ISE6.1i w/SP3).

Par always fails in the final assembly phase with this error message:

"FATAL_ERROR:Guide:basgitaskphyspr.c:255:1.28.20.2 :137 - Guide
encountered a Logic0 or Logic1 signal GLOBAL_LOGIC1_156 that does not
have a driver or load within the module boundary. This problem may be
caused by having a constant driving the input from outside the module
boundary or because a driver or load comp did not meet the par-guiding
criteria."

When I open the .ncd fo the placed and routed module in FPGAEditor and
look at GLOBAL_LOGIC1_156, it's directly connected to a VCC site that is
definitely WITHIN the module boundary, as is the entire signal and all
components it is connected to.

Has anyone else encountered this? I could find nothing about this on
Xilinx's website, and the error message itself is not particularly
helpful. If a "driver or load comp did not meet the par-guiding
criteria", how can I find out WHICH component is responsible, and what
can I do about it?

cu,
Sean
