None in our deployment, albeit we're still on 12.2(52)EY2.

Then again, on ingress, we match all; on egress, we either 
match all or DSCP/EXP, depending on what service is down 
that EVC.

Yes, don't attach your Dell laptop to the console port of a 
box running 12.2(anything) - it will self-reboot. This is a 
known issue.

Also, in many cases, the user-facing ports don't record 
traffic statistics. 'load-interval' won't help. The uplink 
ports always record statistics just fine, though.

We've also been struck by an interesting one that Cisco 
still can't figure out. Initial configuration contains the 
'name' option to the 'ip route' command. Log into the 
switch, make a change, and the 'name' portion disappears. We 
caught this on RANCID, showed it to Cisco, but they can't 
reproduce it. It's still happening today, as we have tons of 
these boxes.
