I don't know but I'm just using AI aka Claude Code that is able to reverse engineer those errors on the fly...

Indeed, it can quickly disassemble the ROM, find where the PC landed, then the source line... But in this case the corruption happened well before: con-handler.c stores an IORequest struct inside its instance, just before various settings. This request was initialized by copying an IOExtSer, with a longer length, and thus serial.device thought it would be ok to scribble all over the context of con-handler 🙂

Why use Claude when we have you 😄
