Is this the bug diagnosed by Bodo Stroesser time ago, or only it looks similar? I recall vaguely that in that bug RCX was corrupted. And what is the impact on UML (Bodo said his bug would affect SKAS behaviour)? Above all, how can UML run in SKAS0 mode with this bug (if it can)? -- Inform me of my mistakes, so I can add them to my list!
