Hello, can anyone still experiencing this on the 4.4 kernel please test with the kernel from this PPA: https://launchpad.net/~ddstreet/+archive/ubuntu/lp1723127 Test kernel version is 4.4.0-112.135+hf1723127v20180206b2
If anyone would like to test with the 4.13 kernel please let me know and I can build it with the recent upstream patch (248de22e638f10bd5bfc7624a357f940f66ba137) that may finally fix this. -- 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/1723127 Title: Intel i40e PF reset due to incorrect MDD detection (continues...) Status in linux package in Ubuntu: In Progress Status in linux source package in Xenial: In Progress Bug description: This is a continuation from bug 1713553; a patch was added in that bug to attempt to fix this, and it may have helped reduce the issue but appears not to have fixed it, based on more reports. The issue is the i40e driver, when TSO is enabled, sometimes sees the NIC firmware issue a "MDD event" where MDD is "Malicious Driver Detection". This is vaguely defined in the i40e spec, but with no way to tell what the NIC actually saw that it didn't like. So, the driver can do nothing but print an error message and reset the PF (or VF). Unfortunately, this resets the interface, which causes an interruption in network traffic flow while the PF is resetting. See bug 1713553 for more details.
