From 436f137975507b0baab0859a253c3c9332c22f62 Mon Sep 17 00:00:00 2001 From: Michael Chan Date: Tue, 13 Feb 2007 12:16:45 -0800 Subject: [PATCH] [TG3]: Save MSI state before suspend. This fixes the following problem: http://bugzilla.kernel.org/show_bug.cgi?id=7969 The MSI state needs to be saved during suspend. PCI state saved during tg3_init_one() does not contain valid MSI state because MSI hasn't been enabled. Signed-off-by: Michael Chan Signed-off-by: David S.
