Bug Description

On a default install the touchpad does not work. Adding "i8042.noloop" to the kernel parameters does get the touchpad working.

The problem here appears to be caused by an improper Chassis Type in the DMI table. The problem we're working around with i8042.noloop is in code that is actually not supposed to be enabled for any laptops, but this DMI table does not indicate that it is a laptop, as indicated by "dmi.chassis.type: 1" or ...

  $ sudo dmidecode -s chassis-type

I believe that if the chassis-type was any of "{Portable, Laptop, Notebook, Sub-Notebook}" (types 8, 9, 10, and 14 respectively) then the touchpad would work correctly without requiring any special boot option.

Having determined that the observed "missed key-release events" problem happens regardless of i8042.noloop, I've submitted that issue as a separate bug report LP: #607350.

Attached patch adds this machine to the dmi_noloop_table (effectively enabling i8042.noloop internally as intended for all laptops). This patch has been submitted to the linux-kernel and ubuntu-kernel mailing lists for review.

The abovementioned patch has been included upstream in kernel 2.6.35-rc6. From the changelog:

    Input: i8042 - add Gigabyte Spring Peak to dmi_noloop_table

    Gigabyte "Spring Peak" notebook indicates wrong chassis-type, tripping up
    i8042 and breaking the touchpad. Add this model to i8042_dmi_noloop_table[]
    to resolve.

SRU Justification for Lucid

Impact: The upstream process for stable tree updates is quite similar in scope to the Ubuntu SRU process, e.g., each patch has to demonstrably fix a bug, and each patch is vetted by upstream by originating either directly from Linus' tree or in a minimally backported form of that patch.

The upstream stable patch set is now available and contains fixes for this problem. It should be included in the Ubuntu kernel as well.
