Confirmed that this is still an issue on 18.04.1. I have an HP 705 G1
with the Broadcom 5762. In my case it's a Plex server. Whenever I try to
stream something the interface goes "NO-CARRIER" and the only way to
recover is to reboot. I've tried disabling highdma, tso and gso using
ethtool, iommu=soft kernel parameter, and forcing every combo of
1gbps/100mbps & half/full duplex. Nothing seems to workaround the issue.

Title:
14e4:1687 broadcom tg3 network driver disconnects under high load
Status in linux package in Ubuntu:
Triaged
Status in linux package in Debian:
New
Bug description:
The tg3 broadcom network driver that binds with chipset 5762 goes offline and
unable to recover (even with tg3 watchdog timeout) when network transmit is
under high load. 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.
WORKAROUND: Add udev rule to make the changes permanent in
/etc/udev/rules.d/80-tg3-fix.rules :
ACTION=="add", SUBSYSTEM=="net", ATTRS{vendor}=="0x14e4",
ATTRS{device}=="0x1687", RUN+="/sbin/ethtool -K %k highdma off"
