psmouse.c - synaptics touchpad driver sync problem

[Thorsten Hirsch <t.hirsch@web.de>]

Hi.

I'm having some sync trouble with kernel 2.6.6-rc3-mm1 (and older 2.6
kernels) in combination with Peter Osterlund's synaptics driver:

psmouse.c: TouchPad at isa0060/serio2/input0 lost sync at byte 1
psmouse.c: TouchPad at isa0060/serio2/input0 lost sync at byte 1
psmouse.c: TouchPad at isa0060/serio2/input0 lost sync at byte 1
psmouse.c: TouchPad at isa0060/serio2/input0 lost sync at byte 1
psmouse.c: TouchPad at isa0060/serio2/input0 lost sync at byte 1
psmouse.c: TouchPad at isa0060/serio2/input0 - driver resynched.
psmouse.c: TouchPad at isa0060/serio2/input0 lost sync at byte 4
psmouse.c: TouchPad at isa0060/serio2/input0 lost sync at byte 1
psmouse.c: TouchPad at isa0060/serio2/input0 - driver resynched.

...and so on. This is causing my mouse in X11 to hang, especially when
cpu load is high. The mouse pointer is doing an uncontrollable move and
some other things are hanging for a short moment, too: xmms for example.
(I guess the whole system is hanging, but xmms playing some music is
very easy to monitor)

I'm using the latest synaptics driver (0.13.0) and I've also tried
0.12.5. I wrote a mail to Peter, but he said, that I should write to the
lkml, so here I am. :-)
X11 version is X.org 6.7.0...but I think, that this doesn't matter. I
even had the same problem with XFree86 4.3.0.

Btw, there's no problem when I use standard ps/2 driver in X, but well,
I'm really missing the synaptics features then.

Regards,
Thorsten
