ixgbe diver with high max_vfs prevents pve 2.2 from booting.

[Mitya]

After installing i82599 10-gigabit adapter and setting
cat /etc/modprobe.d/intel.conf

options ixgbe max_vfs=63 LRO=0 FCoE=0
blacklist ixgbevf

server with pve 2.2 stopped booting (freezing at NFS statd starting). After some investigation I found that ip utility showed only first three interfaces (this port should be fourth and all bridges, vlans, etc next). Updating driver to last did no effect. After lowering max_vfs to 42 it seems work fine.

Looks like current pve kernel (2.6.32-17-pve) is affected by https://bugs.launchpad.net/ubuntu/+source/linux/+bug/960497

Would you please fix this?

I can give more info. Say, statd whle freezed, eated 100% CPU with continously doing something via rtnetlink.
