Greetings,
I’m getting the following messages in my journal log whenever Xorg inits. It fails to initialize the GPU although it shows up in lspci and it works with a Dell Precision 5520 laptop on Thunderbolt 3.

Messages:
kernel: NVRM: GPU 0000:06:00.0: RmInitAdapter failed! (0x26:0x56:1423)
kernel: NVRM: GPU 0000:06:00.0: rm_init_adapter failed, device minor number 1

The Machine it works on is a Dell Precision 5520 with Thunderbolt 3

The Machine it does not work on is a Dell Precision 5570 with Thunderbolt 4

The eGPU is a Mantiz with an eVGA RTX3070 installed

I keep thinking there must be either a BIOS Setting that should off/on, or I am missing a kernel param that must be passed at boot for this to get working.

I have tried the follow boot params: nosimplefb, nomodeset, pcie_aspm=off, pci=nommconf

So far nothing has worked to get the eGPU to initialize with Xorg.

Does anyone have any ideas?
This laptop is very new so maybe there is a BIOS bug. I’ve had two BIOS updates in 2 weeks.

TIA

Known issue, requires either a bios update or using the nvidia open kernel modules instead.

@generix Good to know. Thanks for the information. I’ll press Dell for a BIOS update.
