On my Lenovo S10-3C the Keyboard works right up until the kernel loads. It also works if I enable "noapic acpi=off" while in Grub.
Unfortunately this also creates a basically unusable system as the graphics drivers for the laptop require ACPI.
I am able to login with SSH or use a USB keyboard, so if you need any type of logs then let me know what I should get for you.
I am using gentoo-sources 2.6.37 .
Steps to Reproduce:
1.Get Lenovo S10-3C boot Linux
2.Keyboard stops working after Grub.(all built in KB response stops, Caps lock does not light up)
Keyboard should work with apic and acpi enabled.
Keyboard doesn't work when apic and acpi are enabled.(all built in KB response stops, Caps lock does not light up)
Sorry got Actual and Expected results mixed up.
Please attach dmesg and kernel config to this bug.
