Bug ID: 255961
Summary: RPI 3B+ single user mode locks up
Product: Base System
Version: 13.0-RELEASE
Hardware: arm64
OS: Any
Status: New
Severity: Affects Only Me
Priority: ---
Component: arm
Assignee: freebsd-***@FreeBSD.org
Reporter: ***@hotmail.com

I installed FreeBSD-13.0-RELEASE-arm64-aarch64-memstick.img to a new RPI 3B+. I
added packages, users, etc. and ran for a couple of days for burn-in.
Everything went well until I tried to boot single user. It froze during the
boot and the only keyboard sequence I found that worked was <cntl> <alt> <del>.
I re-booted to multi-user and tried "# shutdown now" to get to single user and
had the same result as booting directly to single user mode.
Any suggestions?
