Thanks for checking, although this is not diagnostic for this issue. Block SID should only be enabled after the encryption has taken place - its function is to prevent changes to the configuration once the secure configuration is in place. This isn’t encouraging, per se, but it’s not indicative the issue isn’t fixed. Block SID can also be enabled from the OS via the CLI even if the BIOS doesn’t expose it.
I also doubt it’s been fixed, based on the release notes, although this touches intriguingly close to the issue:
It’s not the same issue, but tangentially related. Not enough for me to spend the time wiping/reinstalling/testing right now though.
Part of what makes this issue so difficult to troubleshoot and test is that it requires a long series of steps to reproduce and verify. I’ve half a mind to get another 990 Pro to test with.
