Hello, I would like to confirm that it's useful to file a new bug for this issue. For me, the problem I'm having is the same as we are discussing in this thread. Would it be just a duplicate?
Maybe I'm missing something, because I don't know the details of the bug hunting process for Ubuntu. Can you please confirm I should open it? In this case, I can add a detailed description and dmesg logs, with debug on and the timeout error message inside. Anyway, I want to report advances in this problem. I have tested a few kernels and patches in the last weeks, and have found one combination that does solve the issue. I also checked that this patch is not yet merged into the latest vanilla stable kernel, version 4.15, released three days ago. But it patches and works also for 4.15, which is just great (at last for me). Will send the details later (or tomorrow), as soon as I get back to my computer.

Call trace: https://launchpadlibrarian.net/204185480/dmesg When this happens, only a reboot would be able to fix it. Sometimes, however, bringing the interface offline and online (via ifconfig) would recover networking. I've also tested with the latest tg3 driver (dec 2014 version) and networking is still problematic. I have also disabled TSO, GSO etc... with ethtool and the bug still surfaces. This bug may be related to the integrated Firmware. Here is the procedure to replicate the issue because it is hard to replicate it under moderate network load. 1. Bootup a machine with a broadcom 5762 NIC (ie. HP DeskElite 705) using a Ubuntu/Kubunu Live CD 14.04-15.04. 2. from another machine: start 5 sessions, repetitively copy (scp with public key authentication) a 70 meg file back and forth to the tg3 machine in each session. (not sure if this is necessary) 3. create a 1GB file on the tg3 machine, with something like dd if=/dev/urandom of=/my/test/file bs=1024 count=$((1024*1000)) 4. from another machine: repetitively scp copy that 1GB file from the tg3 machine. This can be done with something like: while [ 0 ]; do scp -i /my/scp/private.key u...@ip.of.tg3:/my/test/file /tmp done; Networking will mostly goes offline in about 10-30 minutes.
