Hi,

FreeBSD 13.1 running on ARM in AWS doesn’t shut down when receiving a signal through EC2 API. It can be an issue for instances in autoscaling groups because the longer shutdown time might mess with the scaling policies. And it’s an issue for “permanent” instances because it can result in corrupted data on disk.

I found https://reviews.freebsd.org/D24065, which seems to be included in 13.1, although I can’t find it in any release notes. What am I missing? Should shutdown through AWS Console work?
