+    - ATA: A new SATA link-powermanagement-policy will be the default on all
+      Intel mobile chipsets. This can be reverted by passing 
+      "ahci.mobile_lpm_policy=0" on the kernel commandline.
+    - sound: Enable Intel HDA codec power-saving by default with a 1 second
+      timeout. This can be overridden by passing "snd_hda_intel.power_save=0"
+      on the kernel commandline (0 is previously default).
+    - BlueTooth: Enable USB autosuspend for Bluetooth USB devices by default.
+      This can be disabled by passing "btusb.enable_autosuspend=n" on the
+      kernel commandline.
