Bug Description

I was resuming from suspend and suffering from a non-responsive touchpad as described in [1] so I reconnected the mouse driver using

 echo -n "none" | sudo tee /sys/devices/platform/i8042/serio1/drvctl; sleep 1; echo -n "reconnect" | sudo tee /sys/devices/platform/i8042/serio1/drvctl

several times until the mouse worked again. I then switched to Firefox and switched between tabs using a keyboard shortcut when suddenly the system froze completely. I couldn't even switch to a VT using CTRL-ALT-Fx. Using the MagicSysReg keys I could make force the laptop to reboot.

Same behaviour for me on

Distributor ID: Ubuntu
Description: Ubuntu 18.04.3 LTS
Release: 18.04

with kernel:

If I execute the reconnect script manually things are fine, but if I add it as a service and start it with journalctl the system freezes straight after waking up from sleep.
