A long dead thread, but what you can do with suspend to disk, is suspend to disk, swap batteries to a spare, and resume where you were. I'm specifically thinking about my Nokia N900 cell phone. Other reasons I would have liked it, - When the battery level gets critical, suspend to disk rather than killing it when the battery drains, when I'm not at a place to charge. - Swapping SIM cards (it's under the battery). - Airlines, "yes we really mean OFF not (fill in the blank)" -- David Fries <david@xxxxxxxxx> http://fries.net/~david/ (PGP encryption key available) -- To unsubscribe from this list: send the line "unsubscribe linux-omap" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
