I could not quickly return to 10b3 or -head.
My root fs is ZFS. After upgraded to -current, I have executed zfs upgrade.
When I downgrade to 10b3, boot panic at mount root fs.

I'll try reinstall world and kernel of 10b3 or -head.
But I am a little worried that if it fails, then back to -current is
too much trouble.
