Yeah, that one is PM related. If mach-omap2/pm24xx.c is hacked to only enter MPU retention, rather than full chip retention, it works (quick hack below). I suspect it is due to the lack of wakeup support in OMAP2 PM, but of course it could be something else. - Paul >From 98796ac6423302fdb56afa8a0a262fb09e27a1f6 Mon Sep 17 00:00:00 2001 From: Paul Walmsley <paul@xxxxxxxxx> Date: Thu, 9 Feb 2012 13:07:49 -0700 Subject: [PATCH] fix 2420 serial --- arch/arm/mach-omap2/pm24xx.c | 2 +- 1 files changed, 1 insertions(+), 1 deletions(-) diff --git a/arch/arm/mach-omap2/pm24xx.c b/arch/arm/mach-omap2/pm24xx.c index b8822f8..1f959e3 100644 --- a/arch/arm/mach-omap2/pm24xx.c +++ b/arch/arm/mach-omap2/pm24xx.c @@ -245,7 +245,7 @@ static void omap2_pm_idle(void) if (omap_irq_pending()) goto out; - omap2_enter_full_retention(); + omap2_enter_mpu_retention(); out: local_fiq_enable(); -- 1.7.9 -- To unsubscribe from this list: send the line "unsubscribe linux-omap" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
