[OpenAFS] Solaris 10 SPARC hang on shutdown

[Jeff Blaine]

Has anyone experienced hangs at OS shutdown with OpenAFS 1.4.11
and higher on Solaris 10 SPARC and recent recommended patch
clusters (recent = the last 2 months)?

We experienced this while upgrading (9 to 10) a production
server last week and just moved past it for now to get the
box back up.

I have replicated it on a test box now, thankfully.

The console shows nothing past "syslogd: going down on
signal 15" and just stays there forever (from what we
can tell).

Forcing a savecore dump via 'sync' at the {ok} prompt,
then looking, shows the following processes remaining
at that time:
