Description lsg 2018-04-21 20:13:09 UTC
Description of problem:
Randomly, after some time of working correctly, touchpad and trackpoint stops working in thinkpad helix (convertible laptop) 
in previous versions -fedora 25/26, it worked perfectly ok-
worked perfect with kernel 4.9 (see additional info)

Version-Release number of selected component (if applicable):

How reproducible:
nothing particular: just boot fedora in the laptop and after some minutes the touchpad stops working

Steps to Reproduce:

Actual results:
touchpad and trackpoint stops working but is still recognized in gnome-settings

Expected results:
working touchpad-trackpoint

Additional info:

i've found this, maybe related : 

i've already filled a bug in opensuse tumbleweed ( https://bugzilla.opensuse.org/show_bug.cgi?id=1074507 ) and tested kernel 4.9 in debian, opensuse, fedora 26, and it worked perfectly, so it's a regression.

also reported upstream, but no workaround: https://bugzilla.kernel.org/show_bug.cgi?id=198527 

it can be possibly related to this one:

Comment 1 lsg 2018-04-21 20:38:47 UTC
the same happens in F28

Comment 2 lsg 2018-04-22 03:45:13 UTC
After updating to 4.15 in Fedora, it seems to work ok again : will continue testing

Comment 3 lsg 2018-04-22 15:12:21 UTC
the issue continues in 4.15, not so frequently like before but it happens sometimes.
here the output of dmesg before and after the issue
