Hi, I have an Intel S845WD1 motherboard with a 3Ware 74XX or 75XX card and two Intel NICs (for a grand total of 4 Intel NICs) and 512 megs of ECC RAM. The system was quite stable for a while until I upgraded from 4.9 to 4.11. Afterwards, every 14-16 days I would get a panic: page fault. I replaced the RAM with a new 512 meg ECC stick and I also replaced the motherboard yet I still run into problems. While the date on the kernel looks newer, I have used the same kernel config with 4.9 (recompiled to 4.11) and it still crashed. I'm usually quite conservative, so this is a bit surprising to me. I finally got a chance to have a full kernel dump. I also have some other mini-traces by halting the system after a crash and running trace. I'm not sure if it's hardware anymore, and a lot of people tell me it is network card related. I'm not sure if that's the case either, but you guys are the experts. I say this because the system is never under significant stress and it is always doing light network activity as it is a low use file-server. I think it might also be crashing with the net interrupt only because that is the one activity it is probably doing the most often and it might not necessarily be the net code but who knows. I am able to type in any commands for the dump. As a side note, I am also having some trouble loading all the symbols as seen with frame #6. I followed the instructions in http://www.freebsd.org/doc/en_US.ISO8859-1/books/developers-handbook/kerneld ebug-kld.html What happens is it says it is read without any errors, but I still see ?? function calls. In any event, odds are it is the PPPoE module. I tried loading every module from the kldstat output. Thanks in advance! Sorry if I forgot any important information!
