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