Subject: [PATCH] pnpacpi mishandles port io ADDRESS resources
Date: Sat, 10 Jun 2006 10:41:50 -0600	[thread overview]
Message-ID: <20060610164150.GR1651@parisc-linux.org> (raw)


ACPI ADDRESSn resources can describe both memory and port io, but the
current code assumes they're descibing memory, which isn't true for HP's
ia64 systems.
