I have two routers connected via load-sharing PVCs. IP (other that
EIGRP) between the 2 routers works fine. The IP addresses of the
"connected" interfaces (& EIGRP peers) are correctly subnetted & in
the the same subnet. However, I get the following error message on
the remote "IP-EIGRP: Neighbor 192.168.215.82 not on common subnet for
Serial0/1:0.101".
Remote---S0/0:1.101---Telco---ATM1/0.15---Host
Remote S0/0:1.101 = 192.168.215.85 255.255.255.252
Host ATM1/0.15 = 192.168.215.86 255.255.255.252
Here's a config snippet:

Sounds like your service provider has mapped the PVC on ATM1/0.14 to the PVC on the line on Serial0/1:0.101.
This could be because you have the lines coming into the two serial ports reversed or because your service provider made a mistake. I'm inclined to suspect the former :-)
You may be able to verify this by doing a "show cdp neighbor" (assuming you have not disabled CDP). A "show frame-relay pvc" on the remote router would also be informative.
Good luck and good hunting!
