Your tricky problem wakes up my interest ! :-)
At least, I am happy (for you) that you found out a stable situation
until the high CPU root cause is found.
BTW, how much ram do you have on your router ? Could you please issue a
"show version" and a "show running-config" (don't forget to remove any
password, secret and md5) ? Which feature sets did you install with
15.0M and 12.2SRE ?
Cheers,
Y.

Update on this issue:
After combing the config and google, i tried several things to get
CPU usage down including filtering of IP Options, fragments and
reorganizing my ACLs. Even completely disabling the ACL lists and
any filtering did not help. One document mentioned moving to 12.4
train in order to get more information about the packets coming into
the router. I upgraded the router to 12.4.25f (Service provider w/
IPSEC and LI). After the reload, router came up and my high cpu
usage was no longer there. Didn't make any changes to my config from
SRE that was giving me the high CPU or for that matter from 15.0
that was giving me high CPU.
So my question is why? What is different about 12.4 from SRE and
15.0? If i have to stay on 12.4 train, i'd rather be on 12.4T, but
not sure if i'll run back into the same problem.
