Re: [Xen-devel] Serial console problem with Xen 3.0

I've not yet found a good workaround except to disable pnpacpi. It would be nice to have pnpacpi (or some component) detect that Xen is using the
serial port and leave it untouched.

I think this explains the behavior in bug 229 (and possibly 579 as
well).

It's actually fixed in latest -unstable and -testing trees (we simply ignore the IO-APIC write that attempts to mask the interrupt).
