keyboard stops working

[Xiaotian Sun]

Hi,

I'm having a weird problem: the keyboard doesn't work any more after
FC3 boots.  That is, I can enter CMOS and use the keyboard to change
settings.  But once FC3 boots, keyboard stops working, no matter in
the X mode or in the text mode.

I'm using a normal PS/2 keyboard on a Dell Dimension 8250 computer.

Thanks,

Xiaotian
