I may try to do some bisecting between these kernels - but it might probably easily lead to some dead-ends probably :(... Also I'm using mmc debugs for compilation of these kernels - but nothing seems to printed from mmc subsystem at the end of suspend log and the end is still the same - last printed lines: mmc0: card b368 removed PM: Removing info for mmc:mmc0:b368 Zdenek -- To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to majordomo@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
