I compiled 2.6.35-rc3-git7 applying this patch, but the problem continues.

I have an USB keyboard and mouse. For BIOS and lilo the keyboard works normally. However, when the kernel loads, it stops imediately. I can check this by pressing repeatedly the key lock and observing when the light don't blink.

On -rc2 came arbitrarily characters (but only 1 por line) on the text screen. A PS2 keyboard blocks completely as explained above (and also the PS2 mouse t dont work), an USB keyboard worked almost normally in the grafic mode(also the PS2 mouse worked),

But on -rc3 , no kind of keyboard didn't work anymore.

Rebooting with 2.6.35-rc1, everything works normal.

Thus, the error entered between -rc1 and -rc2 , on something what was changed also till -rc3 so that it then become more worse.
