Using 14.04 on a XPS 15z (cypress touchpad), I still have this issue.
It mostly appears after several 2 fingers scrolling.
dmesg | grep mouse

resynced.

Is the patch really included in this
@Kyle Fazzari - it turns out that my laptop has an Alps touchpad rather
than a Cypress one, so the fix would have no effect for me anyway..
Searching for the error message had brought me here, so I presumed it
was the same issue. I've opened up a separate bug for the Alps touchpad
(see #1258837).
@Christopher Penalver: I've confirmed that Joseph's patch has made it
all the way upstream to the base Linux kernel
(http://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git). Is
this issue then resolved? Is anyone still having issues with it?

Kyle Fazzari, thank you for your quick response. Let us keep open the
linux (Ubuntu) task for now, as it would track this issue for being
released in Trusty, for the original reporter Serge Gélinas if he
decided to update to 14.04 hardware enablement stack as per
Kyle Fazzari / Kamal Mostafa, I just wanted to ping you about if the
patch would be submitted upstream to the linux-input mailing list for
upstream inclusion, or you could advise on upstream discussion of this?

@Allan Crooks: It looks like Joseph got it into Raring, so you should
have seen it in a kernel update. Is that not the case?
@Christopher Penalver: I'm not sure where along the line that got set
back to -1, so the fixed version may have actually been pushed upstream
and a mistake made for Raring.
@jsalisbury, that kernel fixes the bug for me.

I have the same issue (Dell XPS 13, Ubuntu 13.04).
Just wanted to add that the messages in /var/log/syslog appear only when
the laptop's _lid is closed_ (I close it when using an external
monitor/keyboard).
When I open the lid the messages immediately and consistently stop.
I guess the lid is

Closing the lid activates the same effect as resting my palm on the

it just Raring?

As of kernel 3.8, it looks like the function has changed and is now
returning -1 instead of 0:
