Thanks. It solves the problem. But, what you point out is quite interesting. We currently have a (not-yet-upstream) rfkill driver for the XO-1.5, which we also put in place for power saving reasons. It operates by calling mmc_stop_host(). In light of your work, I guess that wasn't really turning off the card. So, it would be great if you could get runtime PM working on this combo, and then later we could make a real rfkill driver. I guess you have an XO-1.5 now. I'm happy to help you get started, I guess this is your first time working with an XO. Drop by irc.oftc.net #olpc-devel and I'll happily help you get started booting your own kernel etc. Thanks!
