Have any of these CPU security features (e.g. SGX from Intel) ever ended up working out? Seems like they always have some critical bug which is discovered too late.

It doesn't seem to a bug though? Just that SME with IOMMU disabled doesn't play well with GPU drivers.

  Yes they need to fix the drivers before reenabling SME

  Unfortunately, the headline is misleading, it's technically not (it's still technically a flaw), but you would assume from context that it's a security flaw rather than a chipset I/O flaw.

Yes, eg virtual memory, virtualization, iommu, nx bit, boot security/drm as used in consoles, come to mind.
