Andy,
   This is a big problem if it is not just an isolated issue with this
particular flash card. I think the bobcat migration plan calls for
pulling the compact flash from the bobcat and placing it in the cougar
then reading the configuration from data from that flash into the
cougar's flash. If there is a requirement that only certain flashes will
work in this procedure then major changes need to be made to the process
and plan. This will need to be communicated up the chain. Expect serious
blow-back from those who's job it is to pretend to be concerned.

I am Cc'ing Tim to give him a heads-up.

Houston, we have a problem.

I took the flash card in question and stuck it into my "new" system,
and I got the same problem as reported in the bug.  No other flash card
I have does that.  It's broken.  We may have to set a requirement on
the flash cards that are used for this operation: ie., that they are
qualified for Cougar, since not all CF cards that work on Bobcat work
on Cougar, because Cougar uses interrupts, and Bobcat doesn't.

That said, there may be a problem with the hardware on the latest build
boards, as my new board does not behave the same way as my old board.
I'm still investigating that issue.
