From aa505bba77961634215eb8bdd8ab9f4bd0c6f1d1 Mon Sep 17 00:00:00 2001 From: Cloud Ren Date: Tue, 3 Jul 2012 16:51:48 +0000 Subject: atl1c: fix issue of transmit queue 0 timed out [ Upstream commit b94e52f62683dc0b00c6d1b58b80929a078c0fd5 ] some people report atl1c could cause system hang with following kernel trace info: --------------------------------------- WARNING: at.../net/sched/sch_generic.c:258 dev_watchdog+0x1db/0x1d0() ... NETDEV WATCHDOG: eth0 (atl1c): transmit queue 0 timed out ... --------------------------------------- This is caused by netif_stop_queue calling when cable Link is down. So remove netif_stop_queue, because link_watch will take it over. Signed-off-by: xiong Cc: stable Signed-off-by: Cloud Ren Signed-off-by: David S.
