[Bug 20062] Re: Keyboard non-responsive when using kernel 2.6.12 (breezy)

[Sam]

Hi nigra,

I have been googling a lot to find out the root cause of my problem but
I only found some workaround. I noticed that the problem does not impact
all HT pentium processors (few threads on the same subject, few
solutions or workarounds) and maybe Intel delivered a serie of bugged HT
processors that do not work properly with the standard 686-smp linux
kernels...

Anyway we have the same problem. We have two workarounds:

a) playing with numlock key during kernel boot (not user friendly).
b) disabling the HT features in the bios (a shame).

Other hints found in the web somewhere:

1) use a wifi usb keyboard.
2) disable the ACPI feature in the bios (in my situation, I cannot toggle off this parameter in my bios, thanks to HP).

I currently run a 686 non-smp kernel because I switched off the HT
feature in the bios and the performances are pretty good, but  not as
good as if I had a HT CPU...

If someone has a solution...

Cheers,

Sam
