+From: Tejun Heo <tj@kernel.org>
+Subject: ata_piix: add borked Tecra M4 to broken suspend list
+References: bnc#398270
+
+Tecra M4 sometimes forget what it is and reports bogus data via DMI
+which makes the machine evade broken suspend matching and thus fail
+suspend/resume.  This patch updates piix_broken_suspend() such that it
+can match such case.  As the borked DMI data is a bit generic,
+matching many entries to make the match more specific is necessary.
+As the usual DMI matching is limited to four entries, this patch uses
+hard coded manual matching.
+
+This is reported by Alexandru Romanescu.
