XPS15 9550 crash when connecting TB16 dock after updating bios to 1.2.25
I had my setup working perfectly on Arch Linux before updating my bios. The dock could be plugged and unplogged at will without crashing. After updating to the latest bios (To get the Intel ME vulnerability patch) it doesn't work anymore.
Connected on the dock:
One 1080P screen (HDMI)
Another 1080P screen (Display port)
USB mouse and keyboard
3.5mm jack to sound system
Setup that worked
Setup that crashes
Connecting the dock when the laptop is powered works.
Connecting the dock when the laptop is turned off and booted works
Connecting the dock when the laptop is powered crashes the system
Connecting the dock when the laptop is truned off works, but mouse and keyboard don't work.
Anyone has pointers on how I could resolve this issue?
