I hadn't changed anything (except for the system board which failed recently) and it used to work fine - So I didnt suspect hotplug to be the culprit - another reason for not considering hotplug was it worked the second time with identical setup. What's funny - I rebuilt hotplug - same version - and it works now! Probably it was failing for some reason the first time. Thanks! Parag
