-- 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/1751337 Title: BCM5719/tg3 loses connectivity due to missing heartbeats between fw and driver Status in The Ubuntu-power-systems project: New Status in linux package in Ubuntu: New Bug description: User reported several nodes lost connectivity in several situations, for instance during the netboot, in which a flood of arp traffic happens due to multiple simultaneous boot across the cluster. No stack trace or message is seen, the device just stop receiving packets. In our attempts to reproduce the issue BCM5719 lost connectivity, always only under a heavy arp storm, in the follow situations: - changing MTU - interface configuration (with ifconfig or ip tool) - netboot In order to fix the issue we need to include the upstream patches: 1 - https://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git/commit/?id=748a240c5 which reads: "tg3: Fix rx hang on MTU change with 5717/5719 " 2 - https://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git/commit/?id=506b0a395 which reads: "tg3: APE heartbeat changes" Considering that 18.04 is planned to use linux 4.15 we will need to backport only the second patch. I'll submit it to the ml and post here a reference.
