commit ed746e3b18f4df18afa3763155972c5835f284c5
Author: Rafael J. Wysocki <rjw@...k.pl>
Date:   Sat Feb 10 01:43:32 2007 -0800

    [PATCH] swsusp: Change code ordering in disk.c
    
    Change the ordering of code in kernel/power/disk.c so that device_suspend() is
    called before disable_nonboot_cpus() and platform_finish() is called after
    enable_nonboot_cpus() and before device_resume(), as indicated by the recent
    discussion on Linux-PM (cf.
    http://lists.osdl.org/pipermail/linux-pm/2006-November/004164.html).
    
    The changes here only affect the built-in swsusp.

Now, the remaining test is to try reverting this commit from -rc6. :)
