Can we close this bug based on the above?

Any particular reason you're booting with the following parameters, they
shouldn't be needed AFAICS?:
maxcpus=1 acpi_enforce_resources=lax i915.enable_rc6=1
i915.preliminary_hw_support=1

I think that instead of the processor.max_cstate=2 workaround we should use
idle=halt until BIOS is fixed, this is the last suggestion from Len Brown.

Also was there a decision to test things with i915.enable_guc_submission=1?
Last that I checked this caused problems and it is disabled now by default for
that reason.
