Solved Unable to boot after installing 11.2-RELEASE-p5

[vasechka]

Hi,

This morning I've upgraded two servers with latest security updates which this time were 11.2-RELEASE-p5. Upgrades went exactly same way:

# freebsd-update fetch
# freebsd-update install
# reboot

After reboot, systems got stuck in following screen:

I recently made change to the /boot/loader.conf and though that problem with it -- booted up with the CD, mounted boot system and edited file. Nope -- didn't solve the problem.

I have installed 11.2 with zraid mirror on zroot. And systems were perfectly fine for last couple weeks while I was configuring them.

So, what's this means and how to troubleshoot this?

Using
kern.vty="sc" didn't help.

Thanks.

P5 only fixed a couple of NFS issues. And a few timezone settings. Nothing relating to the boot files, sectors, or anything else.

This was related to the loader --

But I can't figure out how this change affected boot process.

It wasn't related to the upgrade from p4 to p5 — it was related to the fact that I created another zfs pool, which triggered another bug (or feature?).
