Comment 469 for bug 550625

Hi Seth,

Thanks for your work on this. I'm trying out 0.9 right now, and ran into a problem (Dell Precision M4600). It was working fine for about 40 minutes, until the driver (apparently) lost synchronization with the event data. The mouse pointer began jittering slightly, without me touching the touchpad. Putting my finger on the touchpad generated stray click events and wild movement of the pointer.

Doing an rmmod+modprobe restored it to proper behavior. Nothing interesting was written to the kernel log.
