When putting my laptop on a docking station the system did not detect
the external monitor attached via DP. I took the laptop of the station
and put it back on. Still nothing happend so I decided to reboot the
system. I opened a browser when the system froze. The mouse was still
moving but X was dead in all other regards. To see whether something was
alive I tried to switch to the console via Ctr-Alt-F1. Nothing happend
for about 5 to 10 seconds and then the kernel panic came up. I took a
quick photo of the screen which I attached.
My system is running Ubuntu 17.04. I'm using an upstream kernel:
Linux 4.11.11-041111-generic #201707150838 SMP x86_64 x86_64 x86_64
GNU/Linux
My Laptop is a ThinkPad T460s and I'm using the graphics drivers from
intel.
If you need any more information please do not hesitate to contact me!
