--- Comment #50 from Tom Jones <thj@FreeBSD.org> ---
Can someone experiencing this issue try and reproduce from the FreeBSD
installer on a usb stick? I would like to debug this, but (afaict) I don't have
hardware that triggers this issue.

I tried:

- boot latest snapshot installer
- break to shell
- start powerd
- run `openssl speed -multi $(sysctl -n hw.ncpu)`

from by quick reading of this thread that seemed like it should be more than
enough to hang the system, but interactivity was still fine.

If this can be reproduced from the installer then I can try and borrow laptops
to debug on.

I tried to reproduce on an i3 10th Gen NUC NUC10i3FNK
