This was a correct guess. As of mainline,1403, the ia64 kernel booted on a real machine is ticking reliably again. Unfortunately, there is still some problem with UHCI, which is preventing me from controlling the system using a USB keyboard. So HelenOS found two UHCI hc's and two root hubs. uhcirh then attempted to gain control of the hubs. Then I see a series of 6 warnings of the following kind: [uhci] WARN: Endpoint 0:0 both was left behind, removing [uhcirh] WARN: usb_hc_new_device_wrapper: Failed to unregister default pipe Eventually, the last line of output is: [uhcirh] ERROR: Port (0x00000000000647b0 - 0): Faile(-301) to add device: Operation stalled. Any clues? What should be the next debugging step?
