This is a note to let you know that I have just added a patch titled ACPI: EC: Add a quirk for CLEVO M720T/M730T laptop to the linux-3.5.y-queue branch of the 3.5.yuz 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.yuz tree, see https://wiki.ubuntu.com/Kernel/Dev/ExtendedStable Thanks. -Herton ------ From af3af9a88a02b310c8fe837e2b0d1faaccb008ac Mon Sep 17 00:00:00 2001 From: Feng Tang <feng.tang@intel.com> Date: Fri, 28 Sep 2012 15:22:01 +0800 Subject: [PATCH] ACPI: EC: Add a quirk for CLEVO M720T/M730T laptop commit 67bfa9b60bd689601554526d144b21d529f78a09 upstream. By enlarging the GPE storm threshold back to 20, that laptop's EC works fine with interrupt mode instead of polling mode. https://bugzilla.kernel.org/show_bug.cgi?id=45151 Reported-and-Tested-by: Francesco <trentini@dei.unipd.it> Signed-off-by: Feng Tang <feng.tang@intel.com> Signed-off-by: Len Brown <len.brown@intel.com> Signed-off-by: Herton Ronaldo Krzesinski <herton.krzesinski@canonical.com> --- drivers/acpi/ec.c | 16 +++++++++++++++- 1 file changed, 15 insertions(+), 1 deletion(-) -- 1.7.9.5
