a friend in KMD identified this issue a while back and fixed it with urgency; he understood the impact it can have. honestly i think it warrants a hotfix but it's gated by other work. we're still trying to push to get this out asap.
the reason it's intermittent in the field is that, if the external events utility component is unable to locate the pcie filter driver, it'll keep attempting to install one, though it can't since that part has been removed back in april, given that Win10 22H2 (19045) and all versions of win11 ship their own filter driver with the OS, and our version from 2020 was occasionally forced installed, leading to other issues / ux deficits, like getting a dialog on boot on win10 that a system hardware change has occurred, requiring a restart (coinciding with SAM being disabled)
what i'm struggling to understand right now is why there are instances of EEU not being able to find the filter driver. SAM / ReBAR would be inoperable without it. I'm wondering if the old AMD filter driver was present on these impacted systems, though this shouldn't have even been a possibility on win11 at all :s
