I boot my Cubietruck off a SATA drive without issues with any of those intervening releases but it's a SSD so there would be no spin up time compared to spinning rust, I don't have a spare spinning disk to test it with though.

So w/o the mdelay work for you?

I guess the point of this patch was that you need to have the delay, but the time between the two function calls might cover it, and apparently in some case doesn't. So whether it works in one particular case is entirely moot. Maxime

Then, better some more debugging needed in this case. thanks!

I'm not sure why that is needed, if we need the delay, we should add it explicitly, just like this patch does. Maxime

Since it works on particular case, can't we verify non-working area? adding delay is hard for me but look like this patch needed. thanks!
