From: Daniel J Blueman Date: Fri, 13 May 2011 01:04:59 +0000 (+0800) Subject: x86: Make Dell Latitude E5420 use reboot=pci X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=b7798d28ec15d20fd34b70fa57eb13f0cf6d1ecd;p=GitHub%2FLineageOS%2Fandroid_kernel_motorola_exynos9610.git 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 Link: http://lkml.kernel.org/r/1305248699-2347-1-git-send-email-daniel.blueman@gmail.com Signed-off-by: H.
