    Ubuntu 12.04 Freezes on Lenovo L430

    Hi, seems like a common issue accross the board with no real resolution, I have a Lenovo L430 which I purchased recently, I installed 64-bit Ubuntu 12.04 with kernal 3.2.0.30-generic, with unity desktop and im getting system freezes a few times a day, I have to do a hard reset (hold power button down) to reset my machine, the mouse pointer freezes and the laptop is completely unresponsive.

    The action I've taken so far:

    1. Removed Unity desktop, replaced with Xfce
    2. Replaced Open Java with Sun

    I however still got a freeze, very annoying.

    I know allot of people are experiencing these issues at the moment, and upgrading to 3.4 kernal seems to be an option, however im a bit reluctant in case it makes matters worse as I use the latop for work and cant afford to have a load more crashes during my work day.

    Any recommendations?

    The noapic option didnt help, my lappy has crashed already today after about 10 mins of work!

    really trying to isolate whats going wrong, its a total freeze so I cant see anything in the logs, anyone else have any ideas?

    ok, so I set the pci=nocrs option in grub, i then get the following:

    Code:
    PCI: Using host bridge windows from ACPI; if necessary, use "pci=use_crs" and report a bug
    then when i change it back, i get

    Code:
    PCI: Using host bridge windows from ACPI; if necessary, use "pci=nocrs" and report a bug
    you have to be kidding me!

    OK, im hoping that I am not speaking to soon...but the kernel upgrade has seemed to fix the freezing, also reinstalled unity and everything is working fine..

    The workaround is to load the psmouse kernel module with the option proto=exps:
    Code:
    echo "options psmouse proto=exps" | sudo tee /etc/modprobe.d/trackpoint.conf
    Reboot.

    Unfortunately it is impossible to use the middle button for scrolling.

    See LP #967399. You should sign up there as affected.
