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

Subject: MPC83xx and Gianfar Drive Oops
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:
e-99-0-21-1# Oops: Exception in kernel mode, sig: 5 [#1]

After decoding this it looks like the following:
Enter hex value: c01495d4
0xc01495d4:gfar_error(0xc01494bc)+0x118
Enter hex value: c0149748

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