Description Alan Jackson 2006-01-26 19:35:47 UTC

I have this problem both with Redhat and with Gentoo. If I run the SMP kernel, then I get repeated characters under X from keypresses. The mouse also tends to go haywire. Running non-smp kernel fixes the problem.

How is your clock functioning? 
If the clock is ticking faster, or is an unreliable source of time, this may cause your mouse or keyboard to behave this way.
