Environment: W2K8 R2 Cluster with two nodes
VM with FreeBSD 8.2 and the enlightenment drivers installed
VM has a single synthetic NIC configured to automatically acquire an address via DHCP

Live Migrate the VM to a different node in the cluster.
Migration is successful and the VM has network connectivity

Reboot the VM
After a DHCPREQUEST, DHCPNAK, DHCPDISCOVER and DHCPOFFER, the following
messages are continuously displayed on the console:
    ip length 329 disagrees with bytes received 343
    accepting packet with data after udp payload
Enter Ctrl/C to allow the boot process to complete.
Login and issue the command:  ifconfig hn0
Note that hn0 is UP, but does not have an IP address assigned
Issue the command:  dhclient hn0
The following messages are displayed:
    DHCPREQUEST on hn0 to 255.255.255.255 port 67
    ip length 328 disagrees with bytes received 342.
    accepting packet with data after udp payload.
    DHCPNAK from 10.200.40.41
    DHCPDISCOVER on hn0 to 255.255.255.255 port 67 interval 6
    ip length 329 disagrees with bytes received 343.
    accepting packet with data after udp payload.
    ip length 335 disagrees with bytes received 349.
    accepting packet with data after udp payload.
    DHCPOFFER from 10.200.40.41
    DHCPREQUEST on hn0 to 255.255.255.255 port 67
    ip length 335 disagrees with bytes received 349.
    accepting packet with data after udp payload.
    DHCPACK from 10.200.40.41
    bound to 10.200.49.255 -- renewal in 43200 seconds.
The VM now has network connectivity

Reboot the VM
hn0 successfully acquires an IP address during boot.
However, the above udp messages are displayed on the console
during the boot, but not continuously.

Wait 24 hours, reboot, the continuously repeating messages are displayed until Ctrl/C is entered

I think I have seen this bug on the Linux side and fixed it. Haiyang, I recall a bug in Linux where we were seeing bogus trailer bits is this the same bug?
