Add the general Openstack list, sorry for folks who are on both lists...

Hello,
On my grizzly quantum/OVS network node, after I start the
quantum-openvswitch-agent, the system log shows errors as below,
and it repeats every second since then... and the panic messages
continue on even after I stop all openstack daemons, only a system reboot
can clear it out.

The only other message in the syslog that's related to CSUM is the
following:
Nov 5 14:10:44 cldnet01 kernel: lo: Dropping TSO features since no
CSUM feature.
Nov 5 14:10:44 cldnet01 kernel: lo: Disabled Privacy Extensions
(this message appears after starting the l3-agent)
The network host is RHEL6.4, kernel is
2.6.32-358.123.2.openstack.el6.x86_64
All the daemons appear to being running, an instance can start, but
network doesn't work for the instance.
Any wisdom on what's going on?
Thanks,
Xin
