The Surface Pro X can‘t run Memtest86

Thanks for the logs.

We think it may be related to a firmware update this year. As the Surface Pro X was one of the machines we tested before v9.0 (with ARM support) was released.
We will contact Microsoft to see if they can assist with resolving the issue.

In the meantime you could try using old BIOS firmware (e.g. from around Dec 2020), if it is still available.

Bringing back this thread as I am experiencing the same. Note, it's not possible to roll back firmware on Surface devices.

Surface model: Surface Pro X H Model 1876
SAM: 1.303.139.0
UEFI: 7.590.140.0

Logs attached. I am trying to reach out to MSFT Surface team as well.

We confirmed the issue on our own hardware and also contacted Microsoft about the issue in Dec 2021, but they never responded.

We traced it to the UEFI call for reading keyboard input. The system appears to hang before calling any of these functions

gBS->CheckEvent(gST->ConIn->WaitForKey)
gST->ConIn->ReadKeyStroke(gST->ConIn, &Key)
