I also tried fs freezer without any visible effect. The patches from mm I applied to vanilla kernel: add-include-linux-freezerh-and-move-definitions-from.patch swsusp-cleanup-whitespace-in-freezer-output.patch swsusp-freeze-filesystems-during-suspend-rev-2.patch swsusp-thaw-userspace-and-kernel-space-separately.patch Do I need some more patches for this to work? - -andrey -----BEGIN PGP SIGNATURE----- Version: GnuPG v1.4.5 (GNU/Linux) iD8DBQFFWitgR6LMutpd94wRAjh4AKCnGvpzxHuTEj+xKvEP7YhmESkD1wCffCm3 z0ZM59BV8FZUTy/onowVyW8= =Vt7w -----END PGP SIGNATURE----- - To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to majordomo@...r.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
