One of the cases where Tboot hangs is when you have any USB device (drive, keyboard, mouse) plugged in. So to avoid this you need to remove any USB key attached, during Tboot loading process and can plug it back once you are in the OS. HP is working with its vendor to resolve this issue and an Engineering Advisory will soon be posted on its website addressing this issue.
