tru64-unix-managers,

We have a PCI-VME adaptor in a DS20E, that is not working!
The only error that appears, is in the messages file.

The only difference between this node and other similiar nodes in our
system is a non-configurable kernel value in the vba subsystem is set to
DMA_Map_Status = 1 in this machine and set to 0 in the others.
