   Hallo,   
      
   in my BIOS I have now DISABLED "Quick Power On Self Test". That seems to   
   initialize memory   
   (at least the relevant parts of it) in a way that the trap below does not seem   
   to occur any more.   
   Seems that PMSHELL.EXE is using some uninitialized variable that often enough   
   has a value   
   that does not hurt but sometimes it does.   
   BIOS writing some byte pattern to memory seems to cure the problem.
