Subject: ACPI : Use RSDT instead of XSDT by adding boot option of "acpi=rsdt"
X-Git-Tag: v2.6.29-rc1~34^2~4^2
X-Git-Url: http://git.openpandora.org/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=237889bf0a62f1399fb2ba0c2a259e6a96597131;p=pandora-kernel.git

ACPI : Use RSDT instead of XSDT by adding boot option of "acpi=rsdt"

On some boxes there exist both RSDT and XSDT table. But unfortunately
sometimes there exists the following error when XSDT table is used:
   a. 32/64X address mismatch
   b. The 32/64X FACS address mismatch

   In such case the boot option of "acpi=rsdt" is provided so that
RSDT is tried instead of XSDT table when the system can't work well.
