Subject: [PATCH] ia64 IOSAPIC bogus error cleanup
Date: Thu, 11 Oct 2007 19:33:55 +0000 [thread overview]
Message-ID: <470E7AA3.5020908@sgi.com> (raw)
[-- Attachment #1: Type: text/plain, Size: 91 bytes --]
Tony suggested a simplification to my original post on lkml,
the result is this patch.
[-- Attachment #2: MADT2.patch --]
[-- Type: text/x-patch, Size: 1095 bytes --]
On Altix (sn2) machines the "Error parsing MADT" message is
misleading because the lack of IOSAPIC entries is expected.
Since I am sure someone will ask, I have been told that
the chance of this changing anytime soon is close to nil.
