Indeed, when measured using a 60s iperf run, I do see a performance drop, but by 0.5%.

From the original report, the issue happened since 3.17, so close it on trysty because we can't reproduce it on trusty too. I've seen this with mainline since somewhere in v3.17 and on several hardware boards stress testing KVM by running workloads in VMs. ** Changed in: linux (Ubuntu Trusty) Status: Triaged = Invalid -- 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/1425576 Title: Occasional crash in APM xgene enet driver on kernels prior to v3.19 Status in linux package in Ubuntu: Triaged Status in linux source package in Trusty: Invalid Status in linux source package in Utopic: Triaged Bug description: This crash was submitted upstream and a fix was already present, but it didn't land until the 3.19 kernel.

[Kernel-packages] [Bug 1425576] Re: Occasional crash in APM xgene enet driver on kernels prior to v3.19
One final issue is the kernel version you used to test this fix contains a bug that prevents it from booting on arm64 systems. The fix is in the utopic-stable branch to be pulled into the next SRU cycle. The fix was pushed into the latest trusty kernel for a one-off release, 3.13.0-46.76.

[Kernel-packages] [Bug 1425576] Re: Occasional crash in APM xgene enet driver on kernels prior to v3.19
Commit ecf6ba83d wasn't cc'd to stable. I built a Utopic test kernel with a cherry pick of the commit. It can be downloaded from: http://kernel.ubuntu.com/~jsalisbury/lp1425576/ Can you test this kernel to see if it resolves the bug? If it does, we can send a request to the upstream stable maintainers to also pick this commit. Note the test kernel request both the linux-image and linux-image-extra .deb packages. -- 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/1425576 Title: Occasional crash in APM xgene enet driver on kernels prior to v3.19 Status in linux package in Ubuntu: Triaged Status in linux source package in Trusty: Triaged Status in linux source package in Utopic: Triaged Bug description: This crash was submitted upstream and a fix was already present, but it didn't land until the 3.19 kernel.
