Date: Mon, 31 Jul 2006 00:16:21 -0400 From: David Coulson <david@...idcoulson.net> To: netdev@...r.kernel.org CC: linux-kernel@...r.kernel.org Subject: BUG: warning at net/core/dev.c:1171/skb_checksum_help() 2.6.18-rc3 -----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1 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?
