I'm just now realizing that the crashdump above may have been taken too late (when the kernel wasn't locked up anymre), because I could ssh to the server when I took it.
I was seeing the "block nbdX: Attempted send on closed socket" kernel log spam on the serial when I sent the NMI, but _perhaps_ these messages were just earlier messages that the serial was still catching up with.
Anyway, I got 2 new dumps, and these 2 were triggered automaticallt by kernel.softlockup_panic so they might be better.
