[Dell Latitude E6540] ALPS touchpad keeps having state reset

[zwigno]

While using the 'eraser' pointer on my Dell Latitude E6540, the cursor will sometimes instantly jump around randomly and open a few windows. After this happens, it will become completely unresponsive for 10-20 seconds. Sometimes the keyboard will stop responding also. It seems like it is most likely to happen when I bump the trackpad with my palm when using the eraser pointer in the middle of the keyboard. Also - I have always had the trackpad disabled when this happens via the Dell hotkey (Fn-F5). Of course, it has never happened when the laptop is docked and I am using an external keyboard/mouse.

Same problem on my Dell Latitude E6440. But it happends also when touchpad is enabled (via Fn+F5). Here is relevant part from dmesg log:

[ 104.187214] psmouse serio1: GlidePoint at isa0060/serio1/input0 lost sync at byte 1

When this error happends I see also this error in dmesg:

[42282.319939] psmouse serio1: DualPoint TouchPad at isa0060/serio1/input0 lost sync at byte 1
[42282.321094] psmouse serio1: DualPoint TouchPad at isa0060/serio1/input0 lost sync at byte 1

[42282.324162] psmouse serio1: issuing reconnect request

In both cases it happen when I'm using trackpoint.

Would it be possible for you to test the latest upstream kernel? Refer to https://wiki.ubuntu.com/KernelMainlineBuilds . Please test the latest v3.15 kernel[0].

If this bug is fixed in the mainline kernel, please add the following tag 'kernel-fixed-upstream'.

If the mainline kernel does not fix this bug, please add the tag: 'kernel-bug-exists-upstream'.

If you are unable to test the mainline kernel, for example it will not boot, please add the tag: 'kernel-unable-to-test-upstream'.
Once testing of the upstream kernel is complete, please mark this bug as "Confirmed".

Thanks in advance.

[Pali (pali)]

Above my dmesg logs are from 3.15-rc5 kernel. So it is not fixed.

[zwigno (zwigno)]

I've installed 3.15-rc5, but I'm at work and docked for the time being. I'll see if it happens over the weekend.

I hardly used my laptop over the weekend. Not sure if the bug is still there or not.
