EIGRP funny behavior

I have had an issue with EIGRP on a 1760 connecting to a 3550-24. When the
router is rebooted/powered off and back on, EIGRP will not advertise the FA
interface network. I have seen this several times before, but have always
done a shut/no shut to get the route to get inserted back in the RT. I
imagine this is an IOS anomaly as I can't understand why this would be a
part of normal EIGRP operation. Has anyone seen this before? Any other fix
besides an IOS router/switch upgrade? I don't even think this will be the
fix....I've seen this occur on different hardware/software platforms as
well.
Here is a defect description very similar to my problem. But this is with
like 11.something code!
Description of EIGRP Defect CSCdj58676
This defect was introduced by code changes associated with CSCdj28874. This
defect affects redistribution of routes into the EIGRP routing process. The
following types of routes may not be correctly redistributed:
A directly connected route
A static route with the next hop set to an interface
A static route with the next hop set to a dynamically learned route
The defect becomes apparent only after a dynamic event, therefore when
redistribution is initially configured, EIGRP will reflect correct
information in the topology table, however after any sort of dynamic event
(such as an interface-changing state) the topology table is no longer valid
and routing updates sent will be inaccurate.
