Hi, Following this bug report: http://thread.gmane.org/gmane.linux.ports.arm.kernel/468173 and the suggestions from Russell King, I reviewed all the code involving multi-CPU. It ended with this series of patches which should improve the stability of the driver.
The first patch fix a real bug, the other fix potential issues in the driver. Thanks, Gregory Gregory CLEMENT (6): net: mvneta: Fix for_each_present_cpu usage net: mvneta: Use on_each_cpu when possible net: mvneta: Remove unused code net: mvneta: Modify the queue related fields from each cpu net: mvneta: The mvneta_percpu_elect function should be atomic net: mvneta: Fix race condition during stopping drivers/net/ethernet/marvell/mvneta.c | 160 +++++++++++++++++----------------- 1 file changed, 82 insertions(+), 78 deletions(-) -- 2.5.0
