I wonder if 83 probes are really necessary.  Maybe this could be
optimized a bit.

Or if the kernel could be doing something useful during that time. I
don't suppose it's possible to probe two different ide interfaces at
the same time, is it?

Did the patch to move this into a #define ever get merged?  Seems like
a no brainer, as it eliminates a magic number.

No and it won't because it is not a 'magic number' but rather a 'random
number' (see Alan's mail for explanation).

OK, sorry.  Missed that one the first time.

BTW Lee, 48-bit addressing doesn't mean that capacity > 137GB

Contrary is true of course:
if capacity > 137 GB then disk supports 48-bit addressing.

What determines whether 48 bit addressing will be used then?

Availability of 48-bit addressing feature set and host capabilities
(some don't support LBA48 when DMA is used etc.).
