Re: [Xen-devel] Re: logs attached. Re: [Xen-users] Can not find the cdro
Actually, now I look closer it seems that on native the IDE I/O ports are
detected as 0x1860-0x1867, but the Xen kernel is failing to detect this and
is then failing to register at the default 0x1f0, probably because a legacy
ISA IDE driver is registered there. 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).
