Not sure if you will be interested in this, as your plate must be pretty full already, and I am probably the first person to try suspend/resume on ODROID, but: ODROID-U2 fails to suspend/resume. I am testing with rtcwake, trying to raise a wakeup alarm on the internal Exynos4412 RTC. For this, CONFIG_COMMON_CLK_MAX77686 must be disabled (otherwise it disables the upstream 32KHz clock source for the RTC), I also have CONFIG_RTC_DRV_MAX77686 disabled so that there is only one RTC to worry about. Then: rtcwake --utc -m mem -s 10 -v Before this patch, it would totally hang after calling cpu_suspend() (checked with S3C_PMDBG) - not sure if it hangs before sleeping, or if it sleeps but simply fails to wake up. With this patch, now it seems like the RTC alarm does wake up the system after the desired time, however it immediately goes back into uboot rather than resuming into Linux. So this patch does make some progress at least. The power light is on at all times during these tests (not sure if that means anything, but I was wondering if it should go out when the system suspends).
