I am running 12.2(3) on a 7204 VSR with NBAR and ACL. Every time I
change either NBAR or ACL, I run the risk of bringing my T3 serial
interface down. A shut/no shut would bring it back up. Cisco suggested
changing from a named ACL to a number ACL but that did not solve the
problem. Maybe my problem is related to CSCdv06207 though I seem
luckier that the router does not crash.

Just a guess, but it could be CSCdv06207. if you're running NBAR
(service-policy) and ACLs on the same box, it's quite possible. (this
affected us in 12.2(2)T).
from one of our 7206s that got crashed by this bug:
"System returned to ROM by bus error at PC 0x6056D794, address 0x0 at.."
We've been running 12.2(5.4)T (which has a fix for this bug id) for a
month or more happily without the workaround, which is to enter "ip nbar
resources 600 1000 50" or similar (to reduce the regularity of NBAR
garbage collection, reducing the possibility of the race condition that
causes the crash).
