I have narrowed it dow to fix 318394, which adds a refresh option to geom_label. If I undo this fix in today’s stable it works ok.

I'm even unable to "ls /dev". Looks like the geom refresh changes devices from below the system in a way which triggers this reaction. I don't know the geom code and have been unable to find an immediate problem in the commit mentioned above. I'd really like some help to know where to look, or what kind of debugging information is needed. This is quite a bad bug for people running NanoBSD and should be fixed before the release.
