I think you should upgrade your kernel.
Vanilla Linux versions < 2.6.34 are known to be buggy about huge pages.<= br> Huge pages support is important for DPDK and it could be the cause of your<= br> ixgbe problem.
Note that I don't know if this Debian kernel has backported patches to = fix
hugepages support.
