Subject: [PATCHv5 10/11] TEMP: OMAP3: pm: disable / enable PRCM chain interrupts during wakeup from suspend
Date: Tue, 5 Jul 2011 13:27:56 +0300 [thread overview]
Message-ID: <1309861677-2769-11-git-send-email-t-kristo@ti.com> (raw)
In-Reply-To: <1309861677-2769-1-git-send-email-t-kristo@ti.com>
This prevents system hang while attempting to access suspended console. Should
most likely be fixed with proper console locking.
