In my program I have approximately four 3d models running around the screen
at one time.  Each model is around 600 polygons.  After a few seconds I get
the following message:

DMA bus error: code=80908000
MADR[0]=00106084
MADR[1]=0008e1a7
MADR[2]=00bdffe8
MADR[3]=0008c000
MADR[4]=002fa348
MADR[5]=004021c0
MADR[6]=000a05a4

timeout:que=0,stat=524e028a,chcr=00000401,madr=00bdffe8,func=(80029e50)(8009
e5a4,,00000000))

If I replace the models with other models with fewer polygons, the program
works fine.  Also if I only have two of the models at once everything works
OK.  My drawing sequence is as follows:

        DrawSync(0);
        hsync = VSync(1);
        VSync(0);

        GsSwapDispBuff();

        GsSortClear(0, 0, 0, &OT2[buffIdx]);

        GsDrawOt(&OT2[buffIdx]);

Can anyone shed any light as to what this error message means and provide a
solution?  I'd prefer not to have to make new models.
