Yes, it works with sky2. Yes, the USB device that is reported to fail by PM_TRACE shares the interrupt with eth0, which is sk98lin (see my original posting in this thread). > exactly in the usb does it fail? I don't know, all I have is the PM_TRACE output. Meanwhile, tried to remove uhci_hcd before suspend, and wakeup works then. However, my DVB-T box is dead after resume (reloading the driver doesn't work, only unplug/replug the device helps). It works with suspend to disk, though.
