lost scancode in kernel 3.8

[Gator Liu]

I had a new MSI laptop installed ubuntu 13.04(kernel 3.8 and 3.9).
 It hot-key "Fn+F10"(turn on/off) does not work. I debug i8042, and no scancode presented.

However, I change kernel to 3.2( or 3.5) it's hot-key works and i can get scancode (e076, e062).

Would it be possible for you to test the latest upstream kernel? Refer to https://wiki.ubuntu.com/KernelMainlineBuilds . Please test the latest v3.10 kernel[0].

If this bug is fixed in the mainline kernel, please add the following tag 'kernel-fixed-upstream'.

If the mainline kernel does not fix this bug, please add the tag: 'kernel-bug-exists-upstream'.

If you are unable to test the mainline kernel, for example it will not boot, please add the tag: 'kernel-unable-to-test-upstream'.

Howeve, the bugs is not fixed.

Thanks for help

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...

[Gator Liu (gatorliu)]

Sorry everyone.

It is bios problem.
The MSI's BIOS check kernel 3.7 as Win8, then does not send any scancode out.

After I updated bios, everything work well.
