This machine has four NICs running the e1000 kernel module. Other than
the BUG() messages, it seems to be running fine. I was running 2.6.15.4
without any issues on the same hardware, although I noticed the e1000
has been updated (and I went for rc3 since I was hitting the panic in -rc2)
Now, I'm not sure if it also has anything to do with this message:
NAT: no longer support implicit source local NAT
NAT: packet src 10.1.1.1 -> dst 207.166.203.131
Any suggestions as to how to go about debugging this?

No, this in unrelated. This message tries to tell you that the old
behaviour of changing the source address implicitly to the source
address routing would use for a DNATed connection is no longer done.
This behaviour changed in 2.6.11, so if everything worked in 2.6.15,
you should be fine.

This is a known problem with NAT and HW checksum and will probably get
fixed in 2.6.19. The message is just a warning, everything should work
fine.

Several people are reporting this. It's apparently harmless and serves as
a(n odd) way for the net guys to remind themselves that this needs fixing.
It'd be nice to not let this escape into 2.6.18, please?

I'll make sure it doesn't. :)

I would like to see this fixed for 2.6.18, no later.
Either that or disable the bug trap, but taking this route
is severely discouraged. :)

I'm actually updateing my patch for this on top of Herbert's
CHECKSUM_PARTIAL patch right now. Unfortunately I targeted 2.6.19,
so the fixes are on top of a few cleanups (which unconvered a few
unrelated bugs as well). I'll post it when I'm done so we can
decide how to proceed.
