keyboard misses key presses pediodically (about 5 sec)

noticed an issue (was on 10.04 and continues on 10.10)
so keyboard misses presses in deterministic time period (can't precisely say, about 5 sec)
so that makes very complex to write without typos, especially passwords, say you write 'password' and got 'pssword' or 'passord'

my lshw is:
