Hello!

When I run linux on my netbook lenovo s10-3c -- keyboard doesn't work!
keyboard works perfectly in bios, in grub (or lilo), in windows, but
not in linux.
I try linux kernel 2.6.35, 2.6.36, 2.6.37-rc2 -- no way. keyboard doesn't work
I upgrade BIOS up to 3CCN13WW. keyboard doesn't work
All keys are disabled, numlock, capslock... It's seems like keyboard
haven't power.
with Google I find topic [1] where solution is add to kernel opts
'noapic acpi=off' -- Viola! keyboard work. But battery state,
powersaving, powerbutton and other usefull things doesn't work.
So this is not a workaround...
The keyboard seems to get detected but is silent afterwards...  Does the
touchpad work by default?
Touchpad always work.

Could you try a few kernel options: acpi=noirq, pci=noacpi, i8042.reset
and i8042.nomux please?
acpi=noirq -- kernel panic
pci=noacpi -- kernel panic
i8042.reset=1 -- kbd doesn't work
i8042.nomux=1 -- kbd doesn't work

combination of these options also doesn't help.

Need screenshots of kernel panic?
Might be interesting but not much.

If you plug an external USB keyboard and do:

	echo -n "reconnect" > /sys/bus/serio/devices/serio0/drvctl

or

	echo -n "rescan" > /sys/bus/serio/devices/serio0/drvctl

after booting does it revive the keyboard? Also, what does
/proc/interrupts look like?

Thanks.
