+Subject: [PATCH 1/3] UBUNTU: SAUCE: Revert "Fix OMAP EHCI suspend/resume
+ failure (i693)"
+
+This reverts commit 354ab8567ae3107a8cbe7228c3181990ba598aac.
+
+BugLink: http://bugs/launchpad.net/bugs/1017718
+
+Here is the thread where they discuss the issue:
+
+http://comments.gmane.org/gmane.linux.usb.general/66239
+"OMAP: USB : Fix the EHCI enumeration and core retention issue"
+
+Revert will come down in one of the following 3.5rcX, in the mean time
+we do it on our own.
