"Failed to initialize GPU, declaring it wedged!" after drm-next added to Linus' master
Dell XPS 7390 2-in-1, i7-1065G7 CPU, running a recent Mesa master branch. I normally have i915 module loaded as:
options i915 enable_guc=2 to enable HuC.
I run Linus' master, and today drm-next (477f70cd2a6, drm-next-2021-08-31-1) was merged in. I'm up on the latest(?) linux-firmware (6f5aada830d69e9e0). and have no GPU:

Reverting that merge gets me back and restores HW acceleration in Mesa.
So, do I just wait for the latest GuC to be pushed, or is this a symptom of a larger issue (I didn't think IceLake mobile CPUs were capable of GuC Submission)?
Oh, these are my FW versions (before the drm-next merge):
