sgiwd93 multiple disk problem

Hi,
i guess Ryan Murray has stumbled over the multiple disk problem
on one of my machines again - I would like to fix that bug if i am able to.

My first suspicion was garbled DMA transfers which might happen if starting
a new DMA transfer when thge last is still running. So i tried
to add this to 

drivers/scsi/sgiwd93.c:dma_setup

    105 
    106         if (hregs->ctrl & HPC3_SCTRL_ACTIVE)
    107                 BUG();
    108 

This doesnt seem to get triggered. 

Does anyone have another idea what happens ?

     Why is it called "common sense" when nobody seems to have any?
