I've tested this backported driver for basic functionality - boots, can connect to the interface, ran iperf tests and several flent tests - but I can't reproduce this problem, so I can't test to verify this backport and updated firmware actually fixes it.
Anyone who can reproduce this problem, please test the kernel ppa and report success/failure. This backport will never make it into the trusty release without verification that it fixes the problem. -- You received this bug notification because you are a member of Kernel Packages, which is subscribed to linux in Ubuntu. https://bugs.launchpad.net/bugs/1454286 Title: BNX2X firmware an hang on Trusty (3.13) and Utopic (3.16).

WORKAROUND: After providing the user a "linux-lts-vivid" and an updated linux-firmware package (https://launchpad.net/~inaddy/+archive/ubuntu/sf00080928/) the issue was fixed after package installation and power-cycle -> Power cycle is needed since previous firmware hangs HW until it is shutdown. My comments: """ Actually after reading the Changelog for FW 7.10.51 (specifically the part "Chip may stall in very rare cases under heavy traffic with FW GRO enabled.")
