Hello,
I keep getting unexpected exception errors on my IP1000 with builds
        
over
    
the past 6 months or so. The unexpected exception errors are random
        
errors
    
and are different every time, but seem to happen right about the time
        
the
    
vga rom loads. I think it has something to do with x86emu and yabel
        
loading
    
the vga rom. If I change it to boot up with out graphics it boots up
        
every
    
time, no problem. If I enable the vga device (2.0) and allocate vga
        
memory
    
but not load the vga rom it boots up every time no problem. So this
        
tells
    
me it doesn’t like something the rom emulator is doing, right? This
        
is
    
very strange because I do not have this problem with the RM4100… just
        
the
    
IP1000 (brother boards).

        
You could well be tickling a but in either emulator. These are hard to
find. It's handy to have a user-mode wrapper so you can run these
emulators under linux -- much easier to find that way. Is this
possible with YABEL?
      
Could I try something like vbetool?
  
Not right now, but you can connect to coreboot via gdb over serial,
which gives you a user space frontend with single stepping...

    
Do you mean http://www.coreboot.org/Debugging ??
I tried that, but the errors are different everytime and not always in the
exact place so it is hard to put a finger on it using this method.
 
  
Did you try a backtrace in those cases? What did it say?

Stefan
