Tails fails to start with an HP pavillion (broadwell chipset)

A user reported that Tails 3.3 doesn’t start on this computer :

https://support.hp.com/ca-en/document/c04785675

In the boot menu, when the user clicks on the “Start Tails” button, the error message “Error parsing PCC subspaces from PCCT” is displayed for a few seconds and the computer reboots.

The Toubleshooting mode, or adding xorg-driver=intel as a boot parameter doesn’t work around this issue.

the problem is the same with https://nightly.tails.boum.org/build_Tails_ISO_feature-14976-linux-4.14-force-all-tests/lastSuccessful/archive/build-artifacts/

The user was able to start previous versions of Tails and the current Debian-live (9.3).
