Comment 0 for bug 1775875

lsb_release -a
No LSB modules are available.
Distributor ID: Ubuntu
Description: Ubuntu 18.04 LTS
Release: 18.04
Codename: bionic

uname -r
4.15.0-22-generic

How to reproduce:
1) connect dock station
2) disconnect dock station
3) type: systemctl suspend

Result: system doesn't respond. Only Alt + Print Screen + SUB works.

There is a workaround for this issue - disable USB for thunderbolt 3 in BIOS. But this is slightly an overkill.
