There appears to be quite a few bugs with EIGRP in 12.2(4)T.
There is one that sounds similar to this but it's not exactly
the same thing. Still, you might want to try the workaround
just in case.
Try setting 'pulse-time 3' on your serial interfaces. In some
cases, with certain outboard gear, EIGRP has problems with
interfaces that use pulse-time 1 or 2 after a reload. I don't
know what the default pulse-time is, but it might be
enlightening to at least give this a shot.
If I were you, I wouldn't use 12.2(4)T unless you really have
to. Were you the one needing this image to get certain modules
to work? If so, upgrade as soon as you can. It appears that
12.2(8)T is out but I didn't see that it fixed any of the EIGRP
errors.
Good luck, and let us know if you find the answer!
