next in thread | raw e-mail | index | archive | help
Hi all.
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.
Thanx.
