Yes, this is the ixgbe driver. All I did was run my version of
/etc/init.d/{suri,snortd} stop (testing both at the moment), and
both hosts locked up. I had to do a hard reset as the reboot hung
as well.

All the script does is kill zbalance_ipc then snort/suri . Should
I do that in reverse order so zbalance_ipc is killed last?
