Frederik, Lucas, Are both of you using Debian as the base OS install? I know you are changing kernels but I'm wondering what the base install OS is. I agree that the D# state is most likely what the cause of the device not being seen by the system but what's causing the system to have the NIC in the D3 state.
Also, both of you have the exact same Dell laptop right? Is there a BIOS setting in about how the NIC is suspended or put to sleep? The newer kernels may be doing something with the setting where the older kernels didn't care. Can you guys please check?
