If you do show l2stats you can see the 'number of packets to CPU' per
VLAN - which might help you tell if it's a particular VLAN causing the
problem. Typically the things going to the CPU are stuff that will be
flooded, so high levels of broadcast or flooded multicast on a
particular VLAN might be responsible.

The only way to tell for sure what is causing it is to tcpdump the
packets going to the CPU - but you can only so this in debug mode, which
requires getting a debug password from TAC. This is one of the most
annoying things about extreme IMO, particularly as the passwords are
only valid for a short period of time. If you're trying to debug
something intermittent the problem is often gone by the time you can get
hold of someone with the ability to generate the password.
