atkbd.c
 

hello friends,
i have redhat Centos -4.2 (kernel- 2.6.9-34.0.2.EL)installed linux box.on this i have set up my proxy server.
since yesterday it is continuously giving the mesage as,
"atkbd.c:unknown key released ( translated set 2 code 0xff
on isa 0060/serial 0)"
"atkbd.c:'use setkeycodes e07f <keycode>' to make it known"

when this error is displayed on the screen,my keyboard also starts working improperly.

i am unable to figure out exactly what is going wrong.
will u please help me to solve this?
