Hi
I got this panic about 5 minutes ago:
The system is a dual Xeon HTT disabled, 2 dual port em(4) interfaces
based on the 82546GB chip. VLAN and CARP are in use. This looks
similar to the ARP related panic I posted months ago.
Hardware checksum and VLAN checksum offload is enabled. Harware
VLAN tagging is also enabled. This host's network is not particularly
busy ~20Mbits/s.
