Hi Andreas, No, nothing new on this front. I don't have any of this hardware nor do I work for Intel, and nothing I see in the code or published spec would result in hangs. I don't have more cycles to spend on this driver. So I suggest using 'hint.hwpstate_intel.0.disabled="1"' as a workaround indefinitely.
On a private email with Andrey I discussed making disabled="1" the default, and allowing users to opt in with disabled="0" (or perhaps enabled="1", for fewer double negatives). It's not especially satisfying, but would prevent this class of unknown issue with hwpstate_intel(4).
