Check CPU load.
If you have high bcm_RX or something, than you have a lot of traffic
towards CPU that may cause this behaviour.
We had this problem because on one VLAN we have around 800Mbit/s of
ethernet broadcasts (specyfic traffic - mirror from router forwarded
towards vlan).
This (broadcast to CPU even if VLAN is L2 only) is a bug admitted by
extreme, will be corrected one day ;)
In meantime we have a filter that blocks broadcasts to go to CPU on that
vlan.

Marcin
