Hello Brent,
a Service Request is associated to a Service Contract and only CCO accounts associated to that Service Contract can access it.
So I don't think any of us ( the ones not working directly for Cisco) can access your SR.
And this is reasonable.
It is possible using my CCO account to access the Bug Toolkit(go to support and accesss the Bug toolkit) and look for IOS software 12.4.13b platform 7200 and keyword DMVPN starts a search:
if finds 11 bugs
for example it can be:

Dynamic spoke to spoke tunnel fails to establish in daisy-chained DMVPN

"Dynamic spoke to spoke tunnel fails to establish in daisy-chained DMVPN
In a daisy-chained DMVPN (Dynamic Multipoint VPN) environment, if the hub
router does not terminate both the GRE and IPSec tunnels on the same device,
then NHRP (Next Hop Resolution Protocol) traffic from the hub to a spoke
may be forwarded in clear instead of being encrypted, which subsequently
will be dropped on the destination spoke router. This can cause dynamic
spoke to spoke tunnel not to get established."
There is no known workaround at this time.
However, thanks for having signalled a problem that can occur to other network engineers.
Hope to help
Giuseppe
