    Code:
    echo "blacklist btusb" | sudo tee /etc/blacklist-btusb.conf
    echo "/sbin/modprobe btusb" | sudo tee /etc/rc.local
    This basically disables btusb during the modprobe stage in the bootup, and insteads inserts the module at the very end of the bootup.

    FYI - btusb is a Bluetooth USB module, which seems to be having a race condition in timing when booting off SSD causing kernel panics.

    Let me know if this works or does not work for you.

    All I could find was based on the info in the bug report #1041883, one of the folks mentioned about the asus_wmi_rfkill_init() function which seems to be handing the RFKILL switch i.e Fn+F2 key (for Wifi, BT, 3G, etc.). So I tried disabling few modules during the bootup corresponding to these and finally found out a very highly likely module causing the problem.

    More info here:

    Thanks a lot anyway but it didn't work

    Just to confirm, could you try disabling Bluetooth in the BIOS ?

    Press F12 during bootup and I believe the setting is Located Under Advanced Settings menu.

    There was a typo in the previous set of commands - it should instead be:

    Code:
    echo "blacklist btusb" | sudo tee /etc/modprobe.d/blacklist-btusb.conf
    echo "/sbin/modprobe btusb" | sudo tee /etc/rc.local
    In other words, the file blacklist-btusb.conf should be inside the /etc/modprobe.d directory and not just /etc

    BTW, does anyone know if the iwlwifi and Wireless-N mode issue has been fixed in the Quantal kernel ?

    With 54 Mbps G-mode the effective throughput is low especially when I want to transfer data over the network between devices in my home network

    I am running quantal with latest updates, and the wifi-n doesn't look like fixeed to me, I have timespans of multiple seconds where no information is exchanged when using an n wifi

    I think this issue has gotten a whole lot better, I seldom have any problems. Before this would happen all the time, and G was the only stable wireless to use.

    Since the issue is not Ubuntu centric, but rather a problem with the upstream kernel and iwlwifi driver - I tried with openSUSE 12.2 running a 3.6 kernel and I observed that although the connection looks stable - the "Tx Excessive Retries" and "Invalid Misc" counters keeps increasing rapidly.

    @screemo - Is that what you experience as well ?

    Hello all, Im hoping for some help with the function f5+f6 keys.

    I have gotten them working by using the script here:
    https://wiki.archlinux.org/index.php...light_Method_2

    But the problem is that when I go to adjust brightness up it is extremely slow when doing so, but brightness down behaves just as expected..

    Also I was wondering if there were better drivers for the trackpad available? because the multi-touch gestures can sometimes be unpredictable..

    I am running 12.1 and other than that everything seems to work perfectly out of the box..

    Hi,

    I'm considering buying a UX31A (even though the 4GB of ram might be short for Java programming).

    One of the interesting features announced is the very fast sleep-to-wake time of these ultrabooks. In ubuntu, does this work, or is it just in Windows? ie:

    1) What is the average start-up time?
    2) Do you power off or hibernate/suspend? What's the wake-up time?
