Public bug reported: 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.
