Lunar Lake PCIE crashes when connecting EGPU

[Marcus_St]

Hello all,

when I connect a Thunderbolt eGPU to my Lunar Lake XPS 13 (258V), Touchpad, Touchscreen, Wifi, Sound and all USB devices crash. I can only hard shut down the device.

I've tried all the suggestions in the threads of this forum but with the same result as all other reports state.

Things I've tried:

- Plugging in before boot and booting with eGPU connected

- Installing drivers in secure mode

- Removing all GPU drivers and reinstalling

- Reinstalling Windows and using a fresh, plain installation

All drivers and Windows are up to date.

I can confirm that the eGPU works without any issues on a old laptop with Intel 11th gen processor (1185g7).

As there are the same reports by multiple persons with different systems I assume there is a fundamental issue with Lunar Lake systems and Thunderbolt.

I've created the thread as Intel mods asked to create a separate thread.

Hi @Marcus_St,

Thank you for posting here in our community. To effectively diagnose and address the issue you're experiencing,

• Please provide the SSU log report and share it here so I can review your system's configuration. 
• Are there any error message in the Device Manager?
• Have you tried this set up before?

This issue might be related to how Thunderbolt is integrated into your system’s motherboard, rather than an issue stemming directly from the CPU itself. We will figure this out once I have the logs.

I look forward to your response and am committed to resolving your issue promptly. 

Warm regards,
