Comment 20 for bug 1195655

I also tested other kernels below:
linux-image-3.5.7-03050715-generic_3.5.7-03050715.201306210530_amd64.deb
linux-image-3.6.0-030600-generic_3.6.0-030600.201209302035_amd64.deb
linux-image-3.6.11-030611-generic_3.6.11-030611.201212171335_amd64.deb
linux-image-3.7.0-030700-generic_3.7.0-030700.201212102335_amd64.deb
linux-image-3.7.0-030700rc1-generic_3.7.0-030700rc1.201210161007_amd64.deb
linux-image-3.7.10-030710-generic_3.7.10-030710.201302271235_amd64.deb
linux-image-3.7.5-030705-generic_3.7.5-030705.201301280206_amd64.deb

It works in kernel (3.5.7, 3.6, 3.6.11).
It does not work in kernel (3,7.0rc1 and below).

Another thing, Fn+F2(Scancode: 0xe0 0x56 0xe0 0xd6) also can't be catched by i8042 and "showkey" in kernel (3.5 - 3.7), but it work well in kernel 3.8 and 3.10

Hope the infomation is usful...
