xorg loops

Hi all,
Using 8 current from time to time I have an xorg problem.

Getting millions of those messages

(II) Mouse autoprobe: Changing protocol to ExplorerPS/2
(II) Mouse autoprobe: Changing protocol to ImPS/2

the system is unusable. No response from keyboard or mouse any more.



Any idea, what I can do to prevent this from happining?
