NetBSD 1.5R kernel compiled yesterday / 1.5 ALPHA2 userland.
While doing a make release, I got this panic when the build was
unmounting the vnd0 device for the floppy creation.
repeated make release until you get this.
Don't know. We had this problem in LFS due to races at
umount time. It was fixed by putting in proper locking with vfs_busy()
Maybe something similar?
