My Dell Precision 7530 laptop runs Ubuntu 18.04 LTS (I upgraded from the original installation).
For 18.04-specific dell updates, I use: http://dell.archive.canonical.com/updates/, distribution: bionic-dell-service

Today, the laptop rooted after the entire gnome interface froze (mouse/keyboard unresponsive).
In the virtual console (Ctrl-Alt-F1), I saw a bunch of messages scrolling so fast I couldn't do anything.
Switching back to gnome, (Ctrl-Alt-F7), the system rebooted a few seconds later.

`dmesg` shows a bunch of these:

```

According to this page:

This message is related to the Dell Mouse driver:

https://certification.ubuntu.com/catalog/component/input/5313/input%3ADELL0831%3A00044E%3A1220Mouse/

It it helps, my system is configured w/ 3 displays:
- laptop screen
- 2 external monitors connected to a Dell TB18DC dock which connects to the laptop.

I also have a Dell KM717 wireless keyboard/mouse combo.
Normally, this combo *ought* to work with bluetooth but that's been tricky to pair and unreliable.
Fortunately, the Dell dongle works pretty well; however, the dongle is unreliable if I plug it to the TB18DC
(i.e., after a few minutes, either the keyboard or the mouse stops working).
The most reliable is to have the dongle plugged to the laptop directly and pair the keyboard/mouse via the dell-specific wireless mode.

I'm not sure how this pertains to the dell mouse driver though.

Any suggestions?
