I have checked out this commit and it is NOT working.

BTW I did find the same commit in my bisection log, and probably
it was a false negative (I tried a couple of boot for each working kernel
during bisectrion, probably it was not not enough).
I'm going to replay the bisection today; will report back ASAP, to see
if it ends in something which makes sense to you.

For reference the current bisect log.
