System: NetBSD frau-farbissina 1.5B NetBSD 1.5B (FRAU-FARBISSINA) #37: Wed Jul 12 15:54:41 PDT 2000     thorpej@frau-farbissina:/u2/netbsd/src/sys/arch/alpha/compile/FRAU-FARBISSINA alpha

	AlphaServer 1200 5/533, 1G RAM

	While building a NetBSD/alpha 1.5_ALPHA snapshot on my
	AlphaServer 1200, the system crashed with:

	panic: vgonel: not clean

	The traceback is:


	curproc is amd.

	My 1.5_ALPHA sources are on another machine, accessed via
	NFS, mounted with amd(8).

	Any automounted filesystems that amd(8) is attempting to
	unmount at this point should (there are two) should be busy:

	/amd/yeah-baby/u1 -- home directories, there was a shell sitting
	in ~thorpej at the time.

	/amd/swinger/u1 -- where the 1.5_ALPHA sources are, either a
	build was active, or had completed, and a shell was just sitting

	Was building a NetBSD-1.5_ALPHA shapshot over NFS.  I may be albe
	to easily reproduce it by doing this again.

	Not known.
