Date: Wed, 17 Jan 2007 11:07:54 +0800 From: Wang Zhenyu <zhenyu.z.wang@...el.com> To: davej@...hat.com Cc: LKML <linux-kernel@...r.kernel.org>, Keith Packard <keithp@...thp.com>, Eric Anholt <eric@...olt.net> Subject: [PATCH] intel_agp: restore graphics device's pci space early in resume Dave, Currently in resuming path graphics device's pci space restore is behind host bridge, so resume function wrongly accesses graphics device's space. This makes resuming failure which crashed X. So here's a patch to restore device's pci space early, which makes resuming ok with X. Patch against 2.6.20-rc5.
