This is a note to let you know that I have just added a patch titled ath9k: do not link receive buffers during flush 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. -Herton ------ From 627384f21b01455e94d82c396719052a5c1d324c Mon Sep 17 00:00:00 2001 From: Felix Fietkau <nbd@openwrt.org> Date: Wed, 9 Jan 2013 16:16:52 +0100 Subject: [PATCH] ath9k: do not link receive buffers during flush commit a3dc48e82bb146ef11cf75676c8410c1df29b0c4 upstream. On AR9300 the rx FIFO needs to be empty during reset to ensure that no further DMA activity is generated, otherwise it might lead to memory corruption issues.
