DualPoint TouchPad at isa0060/serio1/input0 lost synchronization, throwing 1 bytes away

Hi there,

For a couple of days I have been having this weird issue:

[  156.930963] psmouse serio1: DualPoint TouchPad at

This started (I think) to happen after I upgraded to linux 3.16:

$ uname -a
Linux maester 3.16.0-0.bpo.4-amd64 #1 SMP Debian 3.16.7-ckt2-1~bpo70+1
(2014-12-08) x86_64 GNU/Linux

What's really odd, is that it now also happen when I use an older
kernel (3.14). I have never been able to use the 3.2 kernel on this
machine (issue with the graphic card). To make matter worse, I have
some keyboard issues too (duplicate key events, and minor latency when
typing).

System is: DELL Vostro 3750 (wheezy +  backports)

Does that make any sense to anybody ?
Thx,
