More correctly: If I suspend by typing pm-suspend or echo mem >/sys/power/state, then it resumes just fine. If I log in to Gnome and push the suspend button, then it does not resume. This seems to be the case with or without your patch. -rc8 and -rc9 with the original patch 4b4f7280 resume fine no matter how I suspend. --Andy -- 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/
