Being tracked on the Intel DRM gitlab instance already: https://gitlab.freedesktop.org/drm/intel/issues/913 Not sure if we should close this out
on 5.4.8 kernel, my laptop (Razer Blade Stealth Late 2019 IceLake) display would go blank and come back frequently wasn't really sure what was causing this. Thought this had to do with the i915 hang everyone was seeing but the link above provided information about some issue related to Intel Audio. I disabled the power management on the intel audio on TLP the system seems to be more stable now. Can't wait for this issue to be fixed.
