right, I see that. I'm not sure what's generating this plug-in event. could it be that the initramfs in which the resume process is taking place is simultaneously waking up the usb system and initiating resume, in such a way that the state of one of the usb devices is consistently miswritten/misread/something? I've snipped a bit more of the log below -- it shows that the "new device detected" event happens during resume, not suspend. Not sure if htat helps. anyway appreciate all your efforts. matt [ 5.644000] Atomic restore preparation [ 5.648000] Freezing cpus ...
