    atheros AR8151 v2.0 freeze when unplugged

    I am running 12.04 64-bit on a toshiba satellite c655d-s5511 laptop.

    lspci -nn


    Network controller RL8188CE [10ec:8176] (rev 01)
    Ethernet controller Atheros AR8152 v2.0 [1969:2062] (rev c1)

    With a fresh install, if I unplug the ethernet cable, the system freezes and nothing is written to syslog.

    I had got this to stop by installing the driver from realtek version 0005.1230.2011. And the "bleeding edge" driver from linuxwireless compat-wireless-2012-03-12-p, for the "alx" atheros driver. But, I then encountered problems with the proprietary radeon driver and reinstalled.

    Now, with or without a wireless connection, with or without compat-wireless-2012-03-12-p installed, with or without the newer bleeding edge drivers (reinstalling ubuntu each time) and with or without linux-backports-modules-cw-3.3-3.2.0-24-generic, and with or without X running, the system freezes if I unplug the ethernet cable or boot without it plugged in.

    Do you have any idea how to fix this? I would at least like to be able to start the laptop with no network. For that, I tried adding "blacklist atl1c" to /etc/modprobe.d/blacklist-atl1c.conf, but the modules is still installed.

    About the blacklisting idea, I need to run update-initramfs to get the ethernet module to not load. So, a suboptimal solution is to blacklist the ethernet driver before unplugging the ethernet cable...:

    echo blacklist atl1c > /etc/modprobe.d/blacklist-atl1c.conf
    update-initramfs -u
    shutdown -r now

    Then reverse that when I want to plug it in. Whee.

    Running fedora 17 64-bit this is fixed with kernel 3.4.0.

    quite new to the (wonderful) world of linux myself....

    installed ubuntu 10.04 lucid lynx on my new acer aspire 7250 (which i bought with linux linpus, a linux without gui, so no fun for me )
    the Ethernet controller Atheros AR8152 v2.0 didn't work but got the wireless going from installing ath9k from compat-wireless 2012-5-10

    never got the ethernet going (didn't really try because everyone told me to go and get ubuntu 12.04
    so i did...did install on its own immediately ethernet as well as wireless drivers, however...the same thing does happen: it freezes when i take out the fact, i disabled networking for the time being and now reinstalled 10.04 on the side (dual boot) because it doesn't give me any trouble...that is, i get the wireless to work and use that.

    anyhoo...i've done some searching for solutions, it's a bit hard to go through every forum there i now ask you; would you know of a solution for ubuntu 12.04 or should i, like yourself, go for fedora? (what the hell is fedora actually? i'll look into that immediately)
