We really need to get xenial added for its HWE kernels: we have several BootStacks running with them, mainly for latest needed drivers while keeping LTS (mellanox for VNFs as an example)- all these are now obviously at risk on the next reboot.
Note also that recovering from this issue does usually require OOB access to the node, as typically bonded interfaces are used for both mgmt and data planes. -- 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/1679823 Title: bond0: Invalid MTU 9000 requested, hw max 1500 with kernel 4.8 / 4.10 in XENIAL LTS Status in Linux: Unknown Status in linux package in Ubuntu: Triaged Status in linux-hwe package in Ubuntu: Confirmed Status in linux-hwe-edge package in Ubuntu: Confirmed Status in linux source package in Yakkety: In Progress Status in linux-hwe source package in Yakkety: Confirmed Status in linux-hwe-edge source package in Yakkety: Confirmed Status in linux source package in Zesty: In Progress Status in linux-hwe source package in Zesty: Confirmed Status in linux-hwe-edge source package in Zesty: Confirmed Bug description: Since I upgraded the kernel from linux-image-4.8.0-46-generic to linux-image-extra-4.10.0-14-generic I'm facing an issue when I want to change the MTU.
