Deep call trace from PCMCIA CF eject

[Paul Dickson]

I did a scan of my message log for something else, and the call trace
below is what I found instead.  Fortunately I remembered what I was doing
at the time, ejecting and reinserting my CF card in my notebook's PCMCIA
slot.  So I did it again without physically removing the card, and the
call trace below is from that verification.

The CF is accessible after the remounting.

Besides the minor concern about the trace itself, a bigger concern on my
part is how deep the call trace is (60+ levels).  How's it doing for stack
space?

What's ext3 doing on the stack of a vfat card?

I did a "cardctl eject 1" here:
