Doubled events

[Lea Gris]

Hello,

Since kernel 2.6.15.25 I encounter sometime doubled events.
This show up as mouse clicks or key pressed as double (two clicks at 
once or repeated same key two times).

Current setup ia32 Dapper on AMD64 chipset nforce4 (Shuttle SN24P)

I'd like to read if someone here encounter the same problem or know how 
to avoid it ?

Doubled events only happens sparsely.
