[c-nsp] Cisco 7606S PPP Multilink issues

I have a Cisco 7606S router with 8 port spa T1 card, running ios version:
c7600rsp72043-adventerprisek9-mz.122-33.SRC1.bin
Right now i have 2 T1's coming in on the same chassis and we are trying to
use PPP Multilink. The far end equipment is a Cisco 7206 router with IOS
version: c7200-p-mz.123-19.bin
When we enable multilink and place the T1s in the ppp multilink group, the
T1's are up/up, the multilink interface is up/up, however no traffic passes
over the multilink, you cant ping the local or remote end multilink ip
address (/30 subnet).
I have tried just putting 1 t1 in the ppp multi group and leaving the other
alone. When this happens, i get same results; T1 in multilink cant ping and
no traffic, the other t1 not in ppp multilink is up and working fine,
pinging, passing traffic just as expected.
I have a Cisco case open, however so far its not much help, just want to
ensure proper multilink configuration, which isnt that difficult.
doing a sh ppp multilink - tells me the interfaces are active
debug ppp multilink negeotation tells me:
