Thanks, I was hoping for a comparison between memory hotplug on and off with hibernation always off, this seems to be between memory hotplug and hibernation. Anyways looking at this log. The only significant difference I can see is that in the one case a lot of stuff including sdhci get initialized earlier. Presumably the timing is somewhat different related to the USB scanning and the memory hotadd kernel being a bit slower to boot (perhaps due to the increased printks) Perhaps this exposes some races that cause the problem. What these races are I don't know. I would suggest to check with the mmc maintainer. -Andi -- To unsubscribe from this list: send the line "unsubscribe linux-mmc" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
