Folks,
Anyone seen this before ?
We have the MPC8349 based EVM board which has 2 GigEs. IP forwarding is
enabled on the system. The kernel/gianfar is 2.6.11 based.
We were trying to stress the GigE interfaces by sending bidirectional
smartbits traffic.
We observe the following kernel oops:

Any idea on this one ? Any new fixes that went in for such issues ?
Thanks!

Do testing with the latest kernel version,
see if it still have the oops.
