Hello, kernel is 5.3.11-300.fc31 (the one I am using these days, for F30 I don't remember but I  guess the issue was there whatever the kernel) My devices are all 3B+, but I can do tests with 3B also. There is no router between client and server. No packet is lost outut from ping 200 packets transmitted, 200 received, 0% packet loss, time 206903ms rtt min/avg/max/mdev = 0.357/0.453/0.659/0.036 ms I am trying this small test     in a shell :         cd /net/NFSSERVER/directories_path/         while true; do sleep 1; ls -al ; done     in another shell         cd /net/NFSSERVER/directories_path/         dd if=/dev/zero of=./data.dd bs=4k count=1000000 status=progress in the first shell each second, I have a ls command running when I launch the second command, I have no more updates ( ls is hanged) whatever the configuration .... and dd is running with an output such as Output from RPI3B               1227259904 bytes (1.2 GB, 1.1 GiB) copied, 99 s, 12.4 MB/s Output from RPI3B+ & usb ethernet        2765832192 bytes (2.8 GB, 2.6 GiB) copied, 106.039 s, 26.1 MB/s Output from RPI3B+ & native ethernet    378548224 bytes (379 MB, 361 MiB) copied, 8 s, 47.1 MB/s     on the last one the update is also hanged on dd, here is an update                        744927232 bytes (745 MB, 710 MiB) copied, 247 s, 3.0 MB/s with PI3B I was able to ctrl-c the dd command, and ls restarts to loop with PI3B+ & usb ethenet card I was able to ctrl-c the dd command, and ls restarts to loop with RPI3B+ & natif ethernet I cannot ctrl-c the dd command I needed to kill -9 the dd process and I got these messages from journal (and ls restarts to loop) Jan 06 12:02:43 pi12.intranet.net kernel: nfs: server syno01 not responding, still trying Jan 06 12:02:43 pi12.intranet.net kernel: nfs: server syno01 not responding, still trying Jan 06 12:02:43 pi12.intranet.net kernel: nfs: server syno01 not responding, still trying Jan 06 12:02:43 pi12.intranet.net kernel: nfs: server syno01 not responding, still trying Jan 06 12:02:45 pi12.intranet.net kernel: nfs: server syno01 not responding, still trying Jan 06 12:02:45 pi12.intranet.net kernel: nfs: server syno01 not responding, still trying Jan 06 12:02:46 pi12.intranet.net kernel: nfs: server syno01 not responding, still trying Jan 06 12:02:46 pi12.intranet.net kernel: nfs: server syno01 OK Jan 06 12:02:46 pi12.intranet.net kernel: nfs: server syno01 not responding, still trying Jan 06 12:02:46 pi12.intranet.net kernel: nfs: server syno01 OK Jan 06 12:02:46 pi12.intranet.net kernel: nfs: server syno01 not responding, still trying Jan 06 12:02:46 pi12.intranet.net kernel: nfs: server syno01 not responding, still trying Jan 06 12:02:47 pi12.intranet.net kernel: nfs: server syno01 OK Jan 06 12:02:47 pi12.intranet.net kernel: nfs: server syno01 OK Jan 06 12:02:47 pi12.intranet.net kernel: nfs: server syno01 OK Jan 06 12:02:47 pi12.intranet.net kernel: nfs: server syno01 OK Jan 06 12:02:47 pi12.intranet.net kernel: nfs: server syno01 OK Jan 06 12:02:47 pi12.intranet.net kernel: nfs: server syno01 OK Jan 06 12:02:47 pi12.intranet.net kernel: nfs: server syno01 OK Jan 06 12:02:47 pi12.intranet.net kernel: nfs: server syno01 OK Jan 06 12:02:48 pi12.intranet.net kernel: rpc_check_timeout: 397 callbacks suppressed Jan 06 12:02:48 pi12.intranet.net kernel: nfs: server syno01 not responding, still trying Jan 06 12:02:48 pi12.intranet.net kernel: nfs: server syno01 not responding, still trying Jan 06 12:02:48 pi12.intranet.net kernel: nfs: server syno01 not responding, still trying Jan 06 12:02:48 pi12.intranet.net kernel: nfs: server syno01 not responding, still trying Jan 06 12:02:48 pi12.intranet.net kernel: nfs: server syno01 not responding, still trying Jan 06 12:02:48 pi12.intranet.net kernel: nfs: server syno01 not responding, still trying Jan 06 12:02:48 pi12.intranet.net kernel: nfs: server syno01 not responding, still trying Jan 06 12:02:48 pi12.intranet.net kernel: nfs: server syno01 not responding, still trying Jan 06 12:02:48 pi12.intranet.net kernel: nfs: server syno01 not responding, still trying Jan 06 12:02:48 pi12.intranet.net kernel: nfs: server syno01 not responding, still trying I am also doing the test generating a 4GB file locally and scp this file to the NFS server RPI3B     : 100% 4000MB   8.2MB/s   08:06 RPI3B+ & usb ethernet         : 100% 4000MB   8.8MB/s   07:32 RPI3B+ & native ethernet     : scp freezes after a few very slow MB transfered  : "5%  216MB 4.7MB/s" and finally I got client_loop: send disconnect: Broken pipe lost connection I don't think this is a NFS issue but more generaly an issue with the driver of the native ethernet card ??

OK, upgrade done, running now kernel 5.4.7-200.fc31, same issue with scp. Should I open an issue on readhat bugzilla or kernel bugzilla ? Thanks Fox On 1/6/20 12:48 PM, Peter Robinson wrote:

Hi again, I now understand what is going on :) there is a bug within the driver with TCP Segmentation Offload (TSO) the workaround is to disable TSO with the following commands     ethtool -K eth0 tso off     ethtool -K eth0 gso off A patch exists and disables by default TSO with the following comment /* TSO seems to be having some issue with Selective Acknowledge (SACK) that  * results in lost data never being retransmitted.  * Disable it by default now, but adds a module parameter to enable it for  * debug purposes *(the full cause is not currently understood)*.  */ I issued these command and tried again the scp command and it works perfectly. Issue logged here https://github.com/raspberrypi/linux/issues/3395 Thanks a lot Fox On 1/6/20 3:46 PM, Stefan Wahren wrote:
