** Description changed: - 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. Then 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. + 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.

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.
