I agree - it's the 2600ft holding pattern alt that's the problem.
Maybe the descent from 2600 ft is outside the specs for an approach?

I had thought of that, but the PT outbound altitude is 2600 as well.
And since you are allowed to fly a racetrack for the PT, if it's OK for
the PT, it must be OK for the hold.
