Ok, I'll check it out. Thank you very much! By the way, we downloaded and tested one of the Deb packages you created, and it worked quite well. Will check which one was exactly before reporting (almost sure it was the one for xenial).
We managed to reproduce the issue easily by booting into pxe and, after the nic was started (trying to get an ip), we reset the machine and booted into Ubuntu. There is a huge difference by doing this and doing a cold boot, directly into Ubuntu. My hypothesis is that pxe setups the nic in a way that is not the default, by changing one (or more) of the config bits for some register. This same bit(s) is/are not being touched by the tg3 driver without patch. This way, a boot may work sometimes, maybe due to default values not being set by the kernel module tg3 (and being set by pxe code, if it executed before Linux is loaded). Anyway, the unpatched kernel breaks very quickly, while the patched kernel you provided worked out very well. This happens after running pxe. I will check your links soon and return with our results in the next days, hopefully this weekend or next week.

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.
