Anyone seen the case where the input errors exceed the input packets?
This is on a PA-MC-T3 card on a 7507

I did a local loopback and ran some ping tests; I was unable to
generate the errors. I also did some ping tests across the T1 and the
input errors counter did not increase. This has also happened on two
different T1s on the T3. I have opened a Cisco ticket, but I was curious
to know if anyone else has seen this.
