Created attachment 512694 [details] /var/log/messages Hi, my Dell Latitude E7450 crashes with gentoo 4.14 kernels (4.14.8-r1 and 4.14.7) directly after login. This happens only when the laptop is in the docking station. Same thing happens when I try to login first and put it in the docking station afterwards. This seems to be caused by an rfkill event as the wifi is automatically disabled when putting it into the docking station. No problems are observed as long as the docking station is not used. Kernels up to 4.12.12 are working flawless. Jan 2 09:10:24 etkbox systemd[1]: Started Load/Save RF Kill Switch Status.

please move to a more recent kernel 4.14.8-r1 and 4.14.7 have been masked
you could solve the problem by moving to a more recent kernel ?
Hi, sorry for the late reply, I've been on vacation for the last weeks. I'm currently back on kernel 4.12.12 which is working flawless for me. I'm gonna check again with a 4.14.14 kernel and will report if it works.
Hi, Still not working with 4.14.14. Logfile attached.

Please post your entire dmesg. Can you also tell me what firmware version you are using? Look for: Loaded firmware version: XXXX in dmesg

Nevermind, there's enough here

To me it seems it's already fixed in 4.15 because I don't see this crash there anymore. Unfortunately, I'm running into another (unrelated) crash now when using the docking station: https://bugzilla.redhat.com/show_bug.cgi?id=1549042

Original problem appears to be solved going by last comment.
