I have a small home router/nas running nvidia ion platform with onboard = = nfe LAN adapter. About a month ago I changed ISP and setup pppoe client with mpd5.5. Sinc= e = that time my router issues kernel panic once or twice a day with "Fatal trap 12: page fault = = while in kernel mode" and (nfe0 taskq) is the current process. Updating to the latest stable doesn't help. I don=E2=80=99t know what to= do next, = any help would be much appreciated. Below is kgdb backtrace, dmesg outpu= t, = kernel config file, if anything is missing just let me know.
