commit: b7798d28ec15d20fd34b70fa57eb13f0cf6d1ecd From: Daniel J Blueman <daniel.blue...@gmail.com> Date: Fri, 13 May 2011 09:04:59 +0800 Subject: [PATCH] x86: Make Dell Latitude E5420 use reboot=pci
Rebooting on the Dell E5420 often hangs with the keyboard or ACPI methods, but is reliable via the PCI method. [ hpa: this was deferred because we believed for a long time that the recent reshuffling of the boot priorities in commit 660e34cebf0a11d54f2d5dd8838607452355f321 fixed this platform. Unfortunately that turned out to be incorrect. ] Signed-off-by: Daniel J Blueman <daniel.blue...@gmail.com> Link: http://lkml.kernel.org/r/1305248699-2347-1-git-send-email-daniel.blue...@gmail.com Signed-off-by: H.
