Hello,
I've had the same issues on a Dell Latitude 7480 running ubuntu 16.04.
I've made some recent updates last week and the system started to randomly
freeze. I've done the same modifications as above, replacing this into the grub
:
GRUB_CMDLINE_LINUX_DEFAULT="quiet splash
[Expired for linux (Ubuntu) because there has been no activity for 60
days.]
** Changed in: linux (Ubuntu)
Status: Incomplete => Expired

Thank you for caring.
I followed the advice in
https://askubuntu.com/questions/971477/ubuntu-17-10-keeps-locking-up-
and-freezing-mouse-and-keyboard-input-doesnt-wor and added this to my
/etc/default/grub:
quiet splash intel_idle.max_cstate=1
The system is stable since then. According to
Did this issue start happening after an update/upgrade? Was there a
prior kernel version where you were not having this particular problem?
Would it be possible for you to test the latest upstream kernel? Refer
to https://wiki.ubuntu.com/KernelMainlineBuilds . Please test the latest
v4.17
I found that dmesg returns this:
---[ cut ]
...
[0.769467] [Firmware Bug]: ACPI MWAIT C-state 0x0 not supported by HW (0x0)
[0.769532] [Firmware Bug]: ACPI MWAIT C-state 0x0 not supported by HW (0x0)
[0.769586] [Firmware Bug]: ACPI
All available updates to the system have been installed, including the
newest BIOS update. Swap is working.
