We seem to be having the same issue on a new Supermicro server running Ubuntu 26.04. The output is like comment 73.
# lspci |grep -i broad 47:00.0 Ethernet controller: Broadcom Inc. and subsidiaries NetXtreme BCM5720 Gigabit Ethernet PCIe 47:00.1 Ethernet controller: Broadcom Inc. and subsidiaries NetXtreme BCM5720 Gigabit Ethernet PCIe This is a Xen virtual machine server, and it's been running for a week or so, with light load. It happened when the weekly VM snapshot job ran, which caused a lot more traffic and presumably triggered the bug. It's hard to trigger on purpose, so I'm still trying to see if things like disabling TCP offloading works. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1447664 Title: 14e4:1687 broadcom tg3 network driver disconnects under high load To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1447664/+subscriptions -- ubuntu-bugs mailing list [email protected] https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
