whats the relevance of e1000?

I though Herbert had fixed these, and it looks like half the patches
got into 2.6.14.3, but not the fix to the fix committed on 9-6 (not in
2.6.14.* at all)

What are the changeset IDs so I can fix this?

Thanks.

I think the commit id that is missing from 2.6.14.X is
fb5f5e6e0cebd574be737334671d1aa8f170d5f3

but here is the web link if i gave the wrong info

It's in 2.6.14.x I just double checked.

For what it's worth I had these messages for a while and they got
fixed 2 or 3 weeks ago from memory in Dave's 2.6.16 net tree or net2.6
tree.

Is it possible for you to download 2.6.16-rc2 or similar and see if it
goes away?

It'll be better, if I get only patch fixs that problem, not all 2.6.16-rc2.

Oops I didn't read Jesse's message earlier properly.

That patch which probably fixed it is (from his message):
I think the commit id that is missing from 2.6.14.X is
fb5f5e6e0cebd574be737334671d1aa8f170d5f3

This patch is in the linux-2.6.14 stable tree, I just
verified this.

So it must be another problem: I had this message with 2.6.15.2:

KERNEL: assertion (!sk->sk_forward_alloc) failed at net/core/stream.c (279)
KERNEL: assertion (!sk->sk_forward_alloc) failed at net/ipv4/af_inet.c (148)

I just got this same warning on a system running 2.6.14.5. It's been
up for 50 days, quite heavily loaded, and I've seen this only once. 
Should i be conserned ? Could someone tell me what it means ?

This should really be on netdev, so I copied it.

I don't believe this is related to e1000 because we don't mess with
the sock (sk) struct.  Did you try disabling TSO?  I bet the netdev
guys can help.
