This patch does fix the stated problem, but in my testing on an AT91SAM9G25 platform the system would not boot up after a power cycle if the RTC backup battery was in place. This second patch is needed to fix the second issue: > > https://git.kernel.org/cgit/linux/kernel/git/next/linux-next.git/commit/?id=9dcc87fec8947308e0111c65dcd881e6aa5b1673 > > I had seen the failure to boot happen rarely in the past, but after applying the "rtc: rtc-at91rm9200: fix infinite wait for ACKUPD irq" patch the failure to boot from power cycle was happening every time on my system. I then applied the second patch I linked to above and my system would then boot up after a power cycle without issue every time. So I would suggest only applying this patch to 3.10-stable, 3.14-stable and 3.15-stable if the "ARM: at91: fix at91_sysirq_mask_rtc for sam9x5 SoCs" patch linked to above is applied in the same series. Thanks, I've applied the above patch to the tree as well. greg k-h -- To unsubscribe from this list: send the line "unsubscribe stable" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
