I currently have an usb cable mouse connected to the computer and that one 
always works. it's only the keyboard that is failing.

I try booting 2.6.26 five times and there work keyboard without problem. In 
2.6.32-trunk it only works if I tap enter key some times around "Start INIT 
2.85" (or at least until the computer has been left alone for an hour or so). 

I did a module compare, in 2.6.32 there are some extra modules that can be 
releated: bluetooth, btusb and hid_logitech.

When was the last kernel upgrade? (the system is currently up-to-date)
