From e84df485c8e059bc9d8d0691ae6a3deafa1f9350 Mon Sep 17 00:00:00 2001 From: Roger Luethi Date: Tue, 6 Mar 2007 19:57:37 +0100 Subject: [PATCH] via-rhine: set avoid_D3 for broken BIOSes This patch sets avoid_D3 for BIOSes known to be broken. Said BIOSes fail at PXE boot if the chip is in power state D3.
