Peter Anvin" Date: Thu, 21 Jul 2011 11:22:21 -0700 Subject: x86: Make Dell Latitude E6420 use reboot=pci Yet another variant of the Dell Latitude series which requires reboot=pci. From the E5420 bug report by Daniel J Blueman: > The E6420 is affected also (same platform, different casing and > features), which provides an external confirmation of the issue; I can > submit a patch for that later or include it if you prefer: > http://linux.koolsolutions.com/2009/08/04/howto-fix-linux-hangfreeze-during-reboots-and-restarts/ Reported-by: Daniel J Blueman Signed-off-by: H.
