U320 Seagate timeout issues with PRETTY_PRINT enabled ...

[Marc G. Fournier]

We're talking to Seagate right now, to see if there is anything at the
firmware level that can get done, and am trying to provide them with as
much information as we can ... I enabled the AHD_REG_PRETTY_PRINT stuff
yesterday, and the output today is ... is there anything in this that I
can show/point out to them?  Something to indicate, or narrow down, where
the problem may lie?

Thanks ...
