Hi folks...

Seeing a lot of these on my SS2 recently:

dma0: xfer (-1) > req (7)
esp0: !TC [intr c, stat 87, step 4] prevphase 3, resid 400
dma0: xfer (-1) > req (7)
esp0: !TC [intr c, stat 87, step 4] prevphase 3, resid 1000
dma0: xfer (-1) > req (7)
esp0: !TC [intr c, stat 87, step 4] prevphase 3, resid 1000
dma0: xfer (-1) > req (11)
esp0: !TC [intr c, stat 87, step 4] prevphase 3, resid 2000
dma0: xfer (-1) > req (11)
esp0: !TC [intr c, stat 87, step 4] prevphase 3, resid 400
dma0: xfer (-1019) > req (7)
esp0: !TC [intr c, stat 87, step 4] prevphase 3, resid 2000
dma0: xfer (-1) > req (7)
esp0: !TC [intr c, stat 87, step 4] prevphase 3, resid 800
dma0: xfer (-1) > req (11)
esp0: !TC [intr c, stat 87, step 4] prevphase 3, resid 400
dma0: xfer (-1) > req (11)
esp0: !TC [intr c, stat 87, step 4] prevphase 3, resid 2000
dma0: xfer (-1) > req (7)
esp0: !TC [intr c, stat 87, step 4] prevphase 3, resid 800
dma0: xfer (-1019) > req (7)

...but I am NOT seeing them on my DEC 3000/400, which uses the same
back-end driver, and a very similar DMA engine.

Can I assume that the "req (7)" is DMA-enabled target selection?  Sort of
a small transfer, yes?

Ideas?  The machine stays up, and is stable... should I be worrying?  :-)
