This is a note to let you know that I have just added a patch titled xhci: Switch Intel Lynx Point ports to EHCI on shutdown. to the linux-3.8.y-queue branch of the 3.8.y.z extended stable tree which can be found at: http://kernel.ubuntu.com/git?p=ubuntu/linux.git;a=shortlog;h=refs/heads/linux-3.8.y-queue This patch is scheduled to be released in version 3.8.13.24. If you, or anyone else, feels it should not be added to this tree, please reply to this email. For more information about the 3.8.y.z tree, see https://wiki.ubuntu.com/Kernel/Dev/ExtendedStable Thanks. -Kamal ------ From 01de397808557f093bbf5d9237c3e77509016292 Mon Sep 17 00:00:00 2001 From: Denis Turischev <denis.turischev@compulab.co.il> Date: Fri, 25 Apr 2014 19:20:14 +0300 Subject: xhci: Switch Intel Lynx Point ports to EHCI on shutdown. commit c09ec25d3684cad74d851c0f028a495999591279 upstream. The same issue like with Panther Point chipsets. If the USB ports are switched to xHCI on shutdown, the xHCI host will send a spurious interrupt, which will wake the system. Some BIOS have work around for this, but not all. One example is Compulab's mini-desktop, the Intense-PC2. The bug can be avoided if the USB ports are switched back to EHCI on shutdown. This patch should be backported to stable kernels as old as 3.12, that contain the commit 638298dc66ea36623dbc2757a24fc2c4ab41b016 "xhci: Fix spurious wakeups after S5 on Haswell" Signed-off-by: Denis Turischev <denis@compulab.co.il> Signed-off-by: Mathias Nyman <mathias.nyman@linux.intel.com> Signed-off-by: Greg Kroah-Hartman <gregkh@linuxfoundation.org> Signed-off-by: Kamal Mostafa <kamal@canonical.com> --- drivers/usb/host/xhci-pci.c | 2 ++ 1 file changed, 2 insertions(+) -- 1.9.1
