--- Comment #18 from Renaud R. (kernelorg@iopsthecloud.com) ---
My setup:
* Latitude E5570 via dock DisplayPort
* Kernel: https://bugzilla.kernel.org
I randomly have blackscreen and I see in my logs (dmesg):
* i915 0000:00:02.0: [drm] *ERROR* mstb 00000000adcef9b1 port 1: DPCD read on
addr 0x4b0 for 1 bytes NAKed
* [38971.851918] i915 0000:00:02.0: [drm] *ERROR* mstb 00000000adcef9b1 port 1:
DPCD read on addr 0x4b0 for 1 bytes NAKed
My laptop was reinstall from and old ubuntu 18.04 to 20.04. I can't remember
the kernel used in Unbuntu 18.04 but I didn't have this issue.
