hAP ac3 4.26.7.0: new WireGuard tunnel fails, reboot hangs until power cycle

Has anyone else run into this on a hAP ac3 running 4.26.7.0?

Today (Oct. 17) I added a WireGuard server entry on Joe’s KD9USW-RT for our WCARES/ARES trailer client. The tunnel wouldn’t connect. I rebooted Joe’s node through the UI, but it never came back and the purple LED kept flashing. Joe powered it off and back on, and both the node and tunnel came up.

Both nodes were running the same firmware version.

I’ve seen this pattern more than once, though I haven’t isolated a repeatable test.

This looks similar to the new WireGuard server issue in #2824:

The October RC notes also describe a separate reboot freeze affecting some hAP ac3 units on 4.26.7.0:

Does this sound like those two known issues? What’s the recommended workaround or stable upgrade path?
