Hello,
I got the following panic while trying out an iked(8) responder in a VPS
on Hetzner, type CX11. There is no dmesg yet because I left the ddb
console on in case I'm asked to run more commands there. It has 2 vCPUs
and it's running 7.0-stable with errata up to 004. Transcription
follows. Lemme know if I can provide with more information.
