Using SuSE 9.1 Professional with kernel 2.6.11  running on a AOpen 1845
Laptop.

Currently running without APM & ACPI

If I turn either or both on I get an erratic mouse and entries such as
these:
Mar  3 15:06:55 bventer01 kernel: psmouse.c: Mouse at
isa0060/serio2/input0 lost synchronization, throwing 2 bytes away.
Mar  3 15:07:23 bventer01 kernel: psmouse.c: Mouse at
isa0060/serio2/input0 lost synchronization, throwing 2 bytes away.

Kernels 2.6.x all reproduce the above symptoms.  I'm currently running
on 2.6.11

Must say that the occurance of these erratic problems are a lot less in
2.6.11 but they still persist.  I did do a test to see if it was ACPI
related.

With ACPI and APM turned on and when I restart "powersaved" mouse goes
crazy without me touching it.  I'm not too sure how to progress to
locate/fix this problem.

Tnx & Bi

My notebook is an Acer Aspire 1520 (1524) with a Synaptics Touchpad,
model: 1, fw: 5.8, id: 0x9248b1, caps: 0x904713/0x4000

Kernels 2.6.11.11 and 2.6.12-rc6
Synaptics driver 0.14.2

The "lost sync at byte" and "driver resynched" began flooding the logs
when I enabled Sensors --> Temperatures --> thermal_zone [THRC/THRS] in
the system monitor gkrellm. I haven't tried battery monitoring.

There are only occasional mouse pointer jumps, but the logfiles grow
very quickly. I tried reducing the gkrellm updates from 10 times a
second to 2, but it only had a marginal effect. It seems a bit silly
that this powerful notebook (AMD64 Athlon 3400+) can't 'multitask'
correctly.

I thought about just erasing the warning messages from the kernel
source (don't want to disable warn in syslog completely), but when I
found the gkrellm culprit I turned off the monitoring instead,
reluctantly.

My system has no taxing desktop, just a window manager.

Hi!


I still get the following messages and my mouse jumps around weirdly 
making work rather difficult regardless of which 2.6 kernel I use (tried 
2.6.8, 2.6.9, 2.6.10, 2.6.11-rc2 with patch-see below, 2.6.11-rc4):

psmouse.c: Mouse at isa0060/serio4/input0 lost synchronization, throwing 
2 bytes away.
psmouse.c: Mouse at isa0060/serio4/input0 lost synchronization, throwing 
2 bytes away.
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.
psmouse.c: TouchPad at isa0060/serio2/input0 lost sync at byte 1

(using either the touchpad or the connected PS/2 mouse)

I tried the patch Dmitry Torokhov supplied in the message with subject 
"Re: Really annoying bug in the mouse driver" from Jan 27 which 
supposedly fixes this problem. unfortunately it only got worse.

the problem is really annoying with windows sometimes closing because of 
sporadic mouse clicks etc. I would happily try patches and help in 
debugging, so if anyone has an idea or if more info about my 
setup/config is needed, just tell me.


thanks a lot,
Nils
