[BUG] oops in net_rx_action on 64-bit powerpc

I tried booting a post 2.6.27 -git on a Motorola ATCA6101 (very similar to a
Maple board). The first time I booted I got the first log below via the
serial console. I rebooted and got as far as a login prompt. I was able to
log in via the serial console, but then got an almost identical oops again, as
shown in the second log below.
I configed out the gigE drivers for the backplane so the only remaining
network link was the e100 link used for booting, but the problem remained.
Anyone have any idea what might be causing this?
Thanks,
Chris
