>(scsi1:A:0:0): data overrun detected in Data-out phase. Tag == 0x36.
>(scsi1:A:0:0): Have seen Data Phase. Length = 0. NumSGs = 0.
As I mentioned to you the last time you brought up this problem, I
don't believe that this is caused by the aic7xxx driver, but the
aic7xxx driver may be the first to notice the corruption. Somehow
the system is generating disk requests with a zero length buffer
provided to the controller. That is the cause of the data-overruns.
Perhaps there is a problem with the dma mapping operations on your
particular type of Alpha?
