Hi,

I'm currently trying -current NetBSD/amd64 on a new machine we just
purchased (4 846 CPUs, 8GB mem).

This machine has a dual `LSI Logic 53c1030' SCSI controller (mpt(4)
driver) and 2 Hitachi 70GB disks.

During boot, i get a DMA loading error message from this controller :

mpt0 at pci4 dev 1 function 0: LSI Logic 53c1030 Ultra320 SCSI
