To be realistic I probably won't be testing this with different kernels. It's happening on a production laptop which I need daily and is a bit tricky to reproduce. Maybe someone else suffering from the issue can do the tests.
More info: the bug doesn't happen on every boot. Suspend/resume cycles may trigger it. I haven't found a way to reproduce it reliably. -- 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/1733888 Title: iwlwifi Error sending STATISTICS_CMD: time out after 2000ms. Status in linux package in Ubuntu: Incomplete Bug description: This started happening today so probably a new issue caused by a kernel update. Randomly, maybe every 45 minutes wifi disconnects and reconnects. Attached is a log output from dmesg. Looks like issue is in the iwlwifi driver. Disconnect causes TCP connections to drop so it's quite annoying for end user. ThinkPad T460p, up to date kernel on Ubuntu 17.04.
