From 152151daece9d5dfd86e652b95846072c0d2b566 Mon Sep 17 00:00:00 2001 From: Dave Jones Date: Tue, 15 Jul 2008 19:54:53 -0400 Subject: [PATCH] 8139too: Force usage of PIO on OQO2 The OQO model 2 has an RTL8139 from Atheros that doesn't like MMIO. It fails on modprobe, with a 'PCI Bus error' message. Force it to always use polled IO.
