[c-nsp] ATOM problems with vss144

Hi all

Can someone give me a hint. I'm having problems with eompls on an vss setup.
I have central site with the vss and to external sites.
One site with a WS-SUP720-3BXL , and another site with a WS-SUP720-3B.
>From the site with WS-SUP720-3B I have tengig uplink to the vss, and from the
Site with the WS-SUP720-3BXL i have 1Gb uplink to the vss setup.
I'm using to interfaces on each site. One to make the l2tp connection and from this one a loop to another local port for accessing the local vlan.
My problem is, when I setup a eompls connection from the site with the -3bxl sup the udnld on the vss disables the port.
It thinks that the link is unidirectional, but both interfaces works fine if I connect an other switch.
But if i'm doing the same thing from the setup with the -3b it works fine.
It's the same software on both sup, and the modules are the same.
Uplink card on the 720-3b is a WS-X6708-10GE and on the 720-3bxl is a WS-X6516A-GBIC.
On each 6500 setup I use a WS-X6148-GE-TX and on the vss I use a WS-X6724-SFP.
Has anyone experienced something like this ??
How can one get debug information out of the box that can point towards something thats making the error.
Debug udnld doesn't give much sense.


Setup
