 It appears the problem is sucessfully circumvented.
 Secondary evidence suggests GENERIC kernel reboots cleanly (at least
 filesystems are unmounted) as 'dmesg' does not contain messages about
 replaying log on various filesystems.
 I will next have console access to the machine on 30 September 2014
 and can gather conclusive results then.  That is, unless I can get
 someone on-site to watch the console as I shut it down and report
 whether anything strange appears.
 The changes should be pulled up to NetBSD-7 and NetBSD-6.
 The real issue is the attachment of multiple PCI-Host Bridges that
 overlay the existing PCI bus with phantom busses causing duplicate enum-
 eration of already-attached devices.  That is out of scope for this PR.
