>Description:
After first starting X, the track pad does not move the cursor.  Likewise, the mouse buttons don't work.

I see some messages like this in dmesg output:

[    44.092818] pms_input: unusual delay (0.040036 s), scheduling reset
[    46.064589] pms_input: unusual delay (0.040036 s), scheduling reset
[    46.965398] pms_input: unusual delay (0.040036 s), scheduling reset

The system is a Lenovo Thinkpad Carbon X1 (same as in PR 55023).
>How-To-Repeat:
Start X using "startx", try to use the trackpad to move the cursor or press the mouse buttons.  I will occasionally see a little cursor movement, but it generally doesn't work.
>Fix:
My workaround is to move the cursor using the red mouse pad in the middle of the keyboard.  Once I do that, then the track pad and other mouse buttons work normally.
