Hi, This fix introduced a regression with ThunderX nodes (CRB-1S, CRB-2S) and our 10G switch (Extreme Networks x670 10GE L3). We have opened a downstream bug report [1], where we temporarily bypassed this by pinning the kernel to 4.4.0-45. I also tested 4.8 (multiple builds), 4.10 and 4.11-rc1 (vanilla); all are still affected by link training issues with our switch, with 4.11-rc1 not working at all and reporting more issues (logs attached in a different LP comment [2]).
BR, Alex [1] https://jira.opnfv.org/browse/ARMBAND-168 [2] https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1672521/comments/17 -- 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/1630038 Title: thunder nic: avoid link delays due to RX_PACKET_DIS Status in linux package in Ubuntu: Fix Released Status in linux source package in Xenial: Fix Released Status in linux source package in Yakkety: Fix Released Bug description: [Impact] Link establishment is delayed during initialization, possibly resulting in remote fault conditions that may cause the interface to fail to come up. [Test Case] Put the system in a reboot loop and watch for a remote fault condition, or a failure to bring up the link that can only be resolved by reloading the module. [Regression Risk] Patch is to a specific driver that is only used on Cavium ThunderX systems. The patch is upstream, so will have upstream support for regressions.
