Hello Alexander, it seems that the log is keeping all the information that you already shared in the first attachment. Could you reproduce with a clean kern.log, since it shuts I guess a dmesg can't be obtained. To clean kern.log: # rm /var/logs/kern.log # reboot The kern.log will regenerate after boot.

Hi, I would like to confirm this as this also affects not only my client but also my Colleagues (thinkpad T460s and T470s). The Problem seem to occur after a few minutes of inactiviy randomly.

Sounds like the Dock is losing its network connection (I'm assuming its wired to the NIC on the dock) When this issue occurs again, remove the network cable from the dock and try logging in. If it lets you in - The dock may be in some sort of power save mode stopping network connectivity. for more information - https://lenovosupport.org/lenovo-support-number/ -- 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/1727662 Title: [Lenovo ThinkPad T450s] Issues after docking and locking: [drm:intel_cpu_fifo_underrun_irq_handler [i915]] *ERROR* CPU pipe A FIFO underrun Status in Linux: Invalid Status in linux package in Ubuntu: Triaged Bug description: What happens is after I dock my laptop into a Lenovo ThinkPad Ultra Dock Type 40A2 20V, lock it via clicking the lock icon, and wait ~30 minutes, one of the following three things happen ~50% of the time when I come back to unlock it: * Most of the time the computer is found shut down. * Sometimes the notebook screen flickers weirdly and one of the two external monitors show pixelation. * The notebook screen shows the lock screen but is completely frozen.

Christopher, I am trying to provide debugging information for myself and the Ubuntu developers. I have NOT asked anybody to perform a root cause analysis, debug my problem, or perform any video review. I have only asked if the observed behavior in the bug in this thread is similar to the one I am observing because all of the other debug information listed in this report is identical to my situation. At this point I'm giving up on asking here. Maybe you are right and this is the wrong form, my thinking was that it would be helpful for you to know that this issue is not specific to the particular hardware listed here.

Hi Alexander. Thanks for your bug report and all your effort to troubleshoot and fix this weird issue. I'm not using any docking station but I'm experiencing the same behaviour (screen flickering and unable to lock my screen) here on a Lenovo T450s with a Intel HD Graphics 5500 (Broadwell GT2) GPU. It happens both with Ubuntu 17.10 and Fedora (26 and 27) so i'm so I suppose that's a weird bug in the intel driver.

Alexander Kops, couple of issues: 1) To clarify, after the firmware update, is the issue still reproducible with latest mainline? 2) Your upstream post is missing all the information requested by Intel as documented in https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1727662/comments/30 . It makes it most difficult for upstream to help if the information they request isn't provided.

Is there a way to find out via Ubuntu? >Otherwise I have to talk to my company helpdesk about it."

As per Intel's instructions, they want to you to test drm-tip, and provide debugging information. However, you don't have to build it. Instead, pre-built builds are provided as a courtesy by Ubuntu maintainers via https://wiki.ubuntu.com/Kernel/MainlineBuilds Also, don't worry about SSH/netconsole, as that is usually for when the logs aren't giving reasonable hints to root cause.
