+        debug messages from reaching the console during the suspend/resume
+        operations.  This may be helpful when debugging device drivers'
+        suspend/resume routines, but may itself lead to problems, for example
+        if netconsole is used.

+          The driver model started out with a sysfs file intended to provide
+          a userspace hook for device power management.  This feature has never
+          worked very well, except for limited testing purposes, and so it will
+          be removed.   It's not clear that a generic mechanism could really
+          handle the wide variability of device power states; any replacements
+          are likely to be bus or driver specific.
