OK; I tested it, and got the reported hang. I then re-booted & tried again -- this time, outside of the X environment. Big difference I noticed was that the command (the second time around) did output a lot of variables & values; here are the last several reported: kerm.fscale: 2048 kern.devstat.numdevs: 4 kern.devstat.generation: 4 kern.devstat.version: 4 ...and that's where it hung. This is on a -STABLE as of this morning: FreeBSD dhcp-133.catwhisker.org 4.3-STABLE FreeBSD 4.3-STABLE #30: Mon May 28 06:33:53 PDT 2001 root@dhcp-133.catwhisker.org:/common/S2/obj/usr/src/sys/LAPTOP_30W i386 built from sources updated from a local CVS repository that was updated: CVSup begin from cvsup14.freebsd.org at Sat May 26 03:47:01 PDT 2001 CVSup ended from cvsup14.freebsd.org at Sat May 26 03:52:48 PDT 2001 CVSup begin from cvsup14.freebsd.org at Sun May 27 03:47:01 PDT 2001 CVSup ended from cvsup14.freebsd.org at Sun May 27 03:53:36 PDT 2001 CVSup begin from cvsup14.freebsd.org at Mon May 28 03:47:00 PDT 2001 CVSup ended from cvsup14.freebsd.org at Mon May 28 03:53:51 PDT 2001 The machine is my laptop, where I've been tracking -STABLE daily since early March. There's some information about it at http://www.catwhisker.rog/~david/FreeBSd/laptop.html. I have not tried booting in single-user mode to try it yet; I'm willing, if there's reason to believe it might make a difference. I should be able to perform reasonable experiments upon request.
