I expect that the method to wake the system and the fact that resume from S3 fails are independent problems. Likely you can use WOL from S5 and the system will boot normally from poweroff. (same can be said for suspend-to-disk -- S4). Likely you can wake the system from S4/S5 via power or sleep button, and it will fail the same way as it fails via WOL. The way to debug an S3 resume with no video is to use a serial or a firewire console. -Len - To unsubscribe from this list: send the line "unsubscribe linux-acpi" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
