* [BUG] mveta: mvneta_txq_bufs_free NULL pointer dereference @ 2017-11-27 8:47 Sean Nyekjær 2017-11-27 9:00 ` Thomas Petazzoni 0 siblings, 1 reply; 6+ messages in thread From: Sean Nyekjær @ 2017-11-27 8:47 UTC (permalink / raw) To: Thomas Petazzoni; +Cc: netdev Hi Thomas I see you are the maintainer on mvneta :-) I have an Espressobin board, i'm currently running with archlinux for arm. I have been running with 4.13.x mainline, 4.13.x with arch patches, 4.14.0 mainline and 4.14.1 with arch patches. You can see what patches that are applied here: https://archlinuxarm.org/packages/aarch64/linux-espressobin/files To the issue (same with all the kernels) :-) Every 10-14 days, sometimes faster the ethernet stops working. I have a serial debug connected so i can check the logs. The kernel logs contains nothing :-( If i then try to down the interface nasty things happen. Here is my kernel dump: [root@espressobin ~]# ip link set dev eth0 down [ 1339.493220] mvneta d0030000.ethernet eth0: TIMEOUT for TX stopped status=0x0000ffff [root@espressobin ~]# [ 1339.802218] br0:

I'm not sure at all, but could you try to apply https://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git/commit/?id=0d63785c6b94b5d2f095f90755825f90eea791f5 and see if the problem is resolved ?
