Christopher, I have raised
https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1268365

However this bug (896922) was originally created by Matthias after he
was told do do so in similar circumstances on
https://bugs.launchpad.net/ubuntu/+source/linux/+bug/773433, a bug which
is now marked as Expired.  I respect that you want to distinguish
specific individual circumstances but this is a severe problem (I have
had to restart psmouse twice while writing this) and creating separate
unlinked bugs dilutes the impact, and presumably reduces the chances of
it being looked at.  From a quick google I found also these which look
like exactly the same issue:

https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1165089 (raised 5/4/2013, also marked as Expired) and 
https://bugs.launchpad.net/ubuntu/+source/xserver-xorg-input-synaptics/+bug/1198274 (raised 5/7/2013, which you have put a similar comment on)
https://bugs.launchpad.net/ubuntu/+source/xserver-xorg-input-synaptics/+bug/1261133 (raised 15/12/2013, which you have put a similar comment on)

Could we perhaps nominate one of these to be the the master issue and
mark it with an appropriate severity, and mark the others all as
duplicates?

Bug description:
  Since Maverick, 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:
