Re: FreeBSD 13.2-p1 hanging

Well, it may be time to downgrade.  I've cleaned all the fans with 
compressed air, since heat is always a suspect, and disconnected USB 
devices.  Over the past two weeks the host now has an MTBF of about 2 
days.  Always the same symptom; it just freezes.   I enabled SMART on 
the root disk; it seems to be healthy.  I don't see any concerning 
messages in the logs.

I am on FreeBSD 13.2-RELEASE-p1 GENERIC amd64

So, to downgrade to the previous kernel would this be the right 
command-line?

freebsd-update upgrade -r 13.2-RELEASE
freebsd-update install
freebsd-update install
pwd_mkdb /etc/master.passwd
pkg-static install -fy pkg
pkg upgrade -fy
freebsd-update install
reboot
