The reason this code breaking all other systems is the wrong usage of Dekker algorithm in MMC block layer. But actually this code is only for MFLD and was wrapped by MFLD controller quirks. I think the wrong use of any platform specific code maybe can also break other systems. Agree? And if you are still not going to review these patches, let me know. _______________________________________________ MeeGo-kernel mailing list [email protected] http://lists.meego.com/listinfo/meego-kernel
