 Unfortunately, to effectively test the support for the system-wide suspend and
 resume transitions in a driver, it is necessary to suspend and resume a fully
 functional system with this driver loaded.  Moreover, that should be done
-several times, preferably several times in a row, and separately for the suspend
-to disk (STD) and the suspend to RAM (STR) transitions, because each of these
-cases involves different ordering of operations and different interactions with

 the machine's BIOS.
 
 Of course, for this purpose the test system has to be known to suspend and
 resume without the driver being tested.  Thus, if possible, you should first
 resolve all suspend/resume-related problems in the test system before you start

 2. Testing the driver
 
 Once you have resolved the suspend/resume-related problems with your test system
 without the new driver, you are ready to test it:
 
-a) Build the driver as a module, load it and try the STD in the test mode (see:
-Documents/power/basic-pm-debugging.txt, 1a)).
+a) Build the driver as a module, load it and try the test modes of hibernation

-b) Load the driver and attempt to suspend to disk in the "reboot", "shutdown"
-and "platform" modes (see: Documents/power/basic-pm-debugging.txt, 1).
+b) Load the driver and attempt to hibernate in the "reboot", "shutdown" and
+   "platform" modes (see: Documents/power/basic-pm-debugging.txt, 1).
 
-c) Compile the driver directly into the kernel and try the STD in the test mode.

-e) Attempt to suspend to RAM using the s2ram tool with the driver loaded (see:

 Each of the above tests should be repeated several times and the STD tests
 should be mixed with the STR tests.  If any of them fails, the driver cannot be
