This is a note to let you know that I have just added a patch titled drivers/libata: Set max sector to 65535 for Slimtype DVD A DS8A9SH to the linux-3.5.y-queue branch of the 3.5.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-3.5.y-queue If you, or anyone else, feels it should not be added to this tree, please reply to this email. For more information about the 3.5.y.z tree, see https://wiki.ubuntu.com/Kernel/Dev/ExtendedStable Thanks. -Luis ------ From 2369fe5ee3c519da459ee8d40105df6c575cbcdb Mon Sep 17 00:00:00 2001 From: Shan Hai <shan.hai@windriver.com> Date: Mon, 28 Oct 2013 16:08:01 +0800 Subject: drivers/libata: Set max sector to 65535 for Slimtype DVD A DS8A9SH drive commit 0523f037f65dba10191b0fa9c51266f90ba64630 upstream. The "Slimtype DVD A DS8A9SH" drive locks up with following backtrace when the max sector is smaller than 65535 bytes, fix it by adding a quirk to set the max sector to 65535 bytes.
