[Fedora-xen] FC5 - serial console - no characters received by host?

[Nathan]

I ran into the same problem too, see

https://bugzilla.redhat.com/bugzilla/show_bug.cgi?id=185744

boot with pnpacpi=off on the kernel command line and it should work
(serial console works fine for me though I'm using com1 at 115200).

Thanks again to James Morris for finding the workaround for this one!
