[solved] shutdown hang up with laptop-mode-tools and wicd

[ligq]

I install a pure no-multilib 64bit gentoo (tuxonice-sources) on my T400s laptop in last four days. While the installation, I use eth0 to connect the internet, the shutdown and reboot all are OK. But when I switch to wireless connection and disconnect the eth0 connection, I reboot and then I found It will hang up after mount / read only.
I googling a while and try to do a lot of test, at the end I use wicd-kde frontend to set wired-default to lo. The shutdown and reboot change to OK.

But by this way, the disadvantage is that wicd kde frontend always show wired-default not wireless connection.

Is there a way to add a script to call "ifconfig eth0 down" before shutdown?

is this a laptop with e1000e NIC?

solved in Linux 3.3.0

workaround for you, unload the modules before shutdown or
