Comment # 5 on bug 1114588 from Takashi Iwai

OK, then let's try some boot options.  Since it's a laptop keyboard, either
i8042 or atkbd is releated.

First of all, try to pass i8042.reset=1
I guess this shouldn't bring any change on S2RAM, but let's be sure.

Then check i8042.noaux=1 option.  This will disable the touchpad or such, so
test with USB mouse (or only with keyboard).

Also, atkbd.reset=1 might be interesting, too.

Another options would be i8042.dumbkbd=1 and i8042.direct=1
