Still bisecting.
There are actually 3 failure modes:
1. these messages
2. just reboot
3. hang with task hung timeout ot startup or shutdown (during reboot) - 3 of these so far.
I have tried bisecting 1 and 2 together. So far I have this:

Additionally, 6a776e47a045 seems to be bad (just had failure during
complation).
Some something between a6128f47f7940d8388ca7c8623fbe24e52f8fae6 and
6a776e47a045 it seems.
