Okay, I've found a way to reproduce the problem, although I don't know
how helpful it is :)
- Mount a CDROM on the NetBSD/alpha machine
- Connect to the CD's share point from a Windows box (samba-18.104.22.168.3
from pkgsrc installed on the NetBSD machine)
- From the Windows box, open a Microsoft Word file that's on the CD
(Word 2000, if it matters)
- Close the Word file
a) Attempt to unmount the CDROM from the NetBSD machine (i.e. umount
/cdrom). The umount fails with "umount: /cdrom: Device busy", but the
uvn_flush message gets printed.
b) Disconnect from the share, then unmount the CDROM. The umount
succeeds, and the uvn_flush message gets printed.
