Hi! Three things:

- There is no commit with a SHA1 like that in atop Git history and what you shared is too long for a SHA1, it looks more like a SHA256. Did you share the right checksum? The only other way I can read this is that it's a SHA256 checksum of one of the past atop release tarballs or artifacts. I have not yet checked those.

- I have tried finding your tool Bismuth but all I find is things KDE and crypto currencies. Please share a link to the Bismuth that you are working on.

- You technically said that you are working on Bismuth /and/ found something, not that you found the bug /through/ Bismuth. Please clarify if and how that was the case.

Thank you!
