I have been doing some more testing and it appears that I see intermittent suspend failures on Tegra124 with linux-4.4.y. Apparently this issue has always been there and appears to be fixed in v4.5. I am still trying to find a way to fix this. The changes in v4.5 that appear to resolve this are too complex for stable (several patches in Tegra clk drivers). Anyway, ignore this for now, I will see how we can fix or workaround for linux-4.4.y. Jon -- nvpublic
