So there is definitely something odd going on here but tracking it down will probably require adding some kernel tracing (e.g., to ide_hwif_configure(), to determine why it is failing to find the special location of the IDE I/O ports). -- Keir On 1/12/06 6:48 pm, "Liang Yang" wrote: > I just download Xen source and do "make world;make > install;depmod..;mkinitrd...".
