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.
