Public bug reported:
There are a lot of open bug-reports concerning this defect, but due to
the most popular report was closed by developers, with the demand to
open a new report if this persists, I open a new bug-report.
When using the touchpad, it's often not working and stucks for seconds, in
short, it is unusesable.
This bug still happens in Ubuntu 11.10 on a Lenovo L520 with 3.0.0-13-generic.
Its a Synaptics touchpad, maybe it's kernel bug.
Dmesg produces the following output:
