Raven Ridge is the same stepping as Ryzen, i.e. potentially subject to the segfault bug. I'm really curious whether it will manifest there too or not.
It's a pretty generic errata that manifests under load. Compiling happens to be one way that flushes it out pretty reliably (as with many errata), and nerds do a lot of compiling in Linux, but it can and does manifest as general OS and application crashiness even in other operating systems (including in Windows). It's a ticking time-bomb, sooner or later some OS or application update could hit the trigger conditions more regularly.
There's nothing quite like being "the brand that randomly crashes all the time" to build a brand image with your customers. And I'm sure OEMs are going to love handling RMAs for AMD's defective processors.
