 -------------------
 
-Channels are required to be configured prior to starting the test run.
-Attempting to run the test without configuring the channels will fail.
+Channels do not need to be configured prior to starting a test run. Attempting

+channels that are available.
 
 Example::
 
     % echo 1 > /sys/module/dmatest/parameters/run
-    dmatest: Could not start test, no channels configured
+    dmatest: No channels configured, continue with any
 
 Channels are registered using the "channel" parameter. Channels can be requested by their
 name, once requested, the channel is registered and a pending thread is added to the test list.
