RE: System Freezes during Import-Module
We tried to repro the issue you are facing on a Latitude E7270. What we basically did was on a default older BIOS we imported Dell PS provider(DCPP) and did not get any issue(like freezing etc), then we flashed with latest BIOS version 1.13.4. Even here no issues for us.
So requesting you to please share the BIOS version on your machines(you can get it by running msinfo32).Also you can try flashing latest BIOS and verifying if the issue still persists.
