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?
