There are known bugs in HIP compiler that are causing random build failures
when making changes to the Cycles kernel. This is preventing developers from
efficiently making improvements to Cycles.
For now Cycles AMD GPU rendering is disabled in Blender 3.6 until a good
solution is found, so that ongoing work like Principled v2 is not blocked.
We hope this can be resolved later on in the 3.6 release cycle.
