    Ralink rt5390 driver causing kernel panic.

    When running Ubuntu 12.10 (or any os with a kernel 3.5 or greater, this problem also happens in Fedora) I encounter a kernel panic after compiling and installing the latest Ralink driver for the rt5390.

    My laptop is an hp dv6.6135dx.

    Here's what I do:

    (this works perfectly in 12.04)

    Download Ralink's latest driver and rename it.

    Code:
    tar xjvf rt.bz2.bz2
    Edit /os/linux/config.mk to make sure these two below values are accurate.
    Code:
    HAS_WPA_SUPPLICANT=y
    HAS_NATIVE_WPA_SUPPLICANT_SUPPORT=y
    Then the compiling (after installing build-essential and linux-headers-generic of course).

    Code:
    cd rt5390
    sudo su
    make clean
    make
    make install
    modprobe rt5390sta
    exit
    I get some warnings but no errors. I then edit:

    Code:
    /etc/modprobe.d/blacklist.conf
    and add:

    Code:
    blacklist rt2800pci
    blacklist rt2800lib
    blacklist rt2x00pci
    blacklist rt2x00lib
    Then I get a kernel panic on reboot, I've taken a picture since I can't take a screen-shot.

    Please help, I really would like to use 12.10 so I could have access to the latest AMD drivers.

    Re: Ralink rt5390 driver causing kernel panic.

    Are you able to boot at all, even in recovery mode? If so, uninstall rt5390sta:
    Code:
    cd rt5390
    sudo su
    make uninstall
    modprobe -r rt5390sta
    exit
    Then reboot and remove the rt2800pci blacklist and tell us what works or not. I believe in 12.10 and forward that rt2800pci covers your device.

    Unfortunately I can't even log in to the recovery console (ctrl+alt+f1, is that what you even call it?) before the kernel panic occurs. The rt2800pci driver is compatible but drops the wireless connection every 5 minutes.

    Exactly the same over here. I can boot, but it gaves me a kernel panic in 5 minutes or so before it happens. At least the wifi works perfectly before it.

    Thank you very much chili555, you're the master of this!

    I meant when the GRUB menu comes up or you bring it up with the shift key: https://help.ubuntu.com/community/Grub2

    I can even log in, and use the wifi, but the kernel panic happens in 5 minutes or so.
    Uninstalling the rt5390sta module is not an option for me because im a little far from the router and the connection drops a lot with the other module, if I can't fix this I should buy a usb key...

    Alas, I've also tried this but it doesn't really matter since the rt2800pci driver works so poorly.

    Chili,
    Do you know of any steps to improve rt2800pci's resiliency?

    Re: Ralink rt5390 driver causing kernel panic.

    Seeing this make me realize I'm not the only one with this issue so I'm going to report the bug in LinuxMint Launchpad (it's the distribution I use) although it should be the same for Ubuntu since Mint is Ubuntu + some packages.

    I'm gonna post the link here when I finish.

    Cya!

    Certainly. You might try the Ubuntu version of compat-wireless. With a wired ethernet connection temporarily, do:
    sudo apt-get install linux-backports-modules-cw-3.6-quantal-generic
    Reboot and tell us if it's working better.

    You might also try a driver parameter:
    Code:
    sudo modprobe -r rt2800pci
    sudo modprobe rt2800pci nohwcrypt=Y
    If this helps, we'll write a quick file to make it persistent.

    You might also set the router to WPA2 only, not WPA/WPA2 mixed mode. If it's available, try shutting off N speeds in the router.
