From 7588286c13ce04de9ce9b9a844033e07d0e71c93 Mon Sep 17 00:00:00 2001
From: Andy Green <andy@openmoko.com>
Date: Mon, 21 Jul 2008 00:51:15 +0100
Subject: [PATCH] debug-move-dev-info-to-dbg.patch
 Suggested-by: Sean McNeil <sean@mcneil.com>

To see if some subtle race is involved, Sean has tried
removing syslog traffic during resume and found he was
not seeing the resume crash any more.  We're giving it
a try to see if it changes the behaviour for anyone
else.  It would mean we have a pretty fine race in there
somewhere.
