It's hard to tell much without trace, I'll try to check 
changes meanwhile to see what would break.
I appreciate if you can provide your configuration then I
might find something similar around.
In my environment I had to enlarge msgbufsize to be able to
grab enought there.
I would try to set ncr53c9x_dmaselect to 0, to check if it
changes anything.
