Okay, got it working. I used an almost minimal vanilla 2.6.18 with no modules. Almost minimal because I included IDE since I have no initram at hand. But I do not think that makes a difference. I tried out suspend without IDE a few month ago and it did not work either. Looking at the console log and bus-messages attached below it seems that the bus is not initialized during resume. I will try now the early-init patch I got. Hope that gets more information. Any idea what ACPI-debug options to set so we see more what happens during suspend? Maybe that gives a clue too? -Peter ++++++++++++++++++++++++++++++ Bus-changes according to dmesg on the console-host: due to suspend: [4296157.983000] ieee1394: Node changed: 0-01:1023 -> 0-00:1023 [4296157.984000] ieee1394: Node suspended: ID:BUS[0-00:1023] GUID[00c09f00002097ea] due to wakup [4296231.271000] ieee1394: The root node is not cycle master capable; selecting a new root node and resetting...
