Subject: [patch 24/56] ACPI: disable ACPI cleanly when bad RSDP found
Date: Tue, 10 Feb 2009 16:25:04 -0800 [thread overview]
Message-ID: <20090211002504.GY14660@kroah.com> (raw)
In-Reply-To: <20090211002328.GA14660@kroah.com>
[-- Attachment #1: acpi-disable-acpi-cleanly-when-bad-rsdp-found.patch --]
[-- Type: text/plain, Size: 1280 bytes --]
2.6.27-stable review patch. If anyone has any objections, please let us know.
------------------
From: Len Brown <len.brown@intel.com>
commit 9e3a9d1ed8cc8db93e5c53e9a5b09065bd95de8b upstream.
When ACPI is disabled in the BIOS of this VIA C3 box,
it invalidates the RSDP, which Linux notices:
ACPI Error (tbxfroot-0218): A valid RSDP was not found [20080926]
Bug Linux neglected to disable ACPI at that stage,
and later scribbled on smp_found_config:
ACPI: No APIC-table, disabling MPS
But this box doesn't run well in legacy PIC mode,
it needed IOAPIC mode to perform correctly:
http://lkml.org/lkml/2009/2/5/39
So exit ACPI mode cleanly when we first detect
that it is hopeless.
