Since you have an error count in there, I would expect there to be 
something in the error log. Might be worth checking what it says...

Other than that, I have not tried that specific hardware, but I have 
seen similar issues when DMA have been non-working. Are you sure the 
card is in the correct slot? I assume you know about qbus bus 
continuation, as well as the actual backplane layout, and possibly 
jumpers that might need to be put one way or another depending on the 
type of slot, if it is a quad size card...
