loss of PCMCIA ed(4) interface

[M. Warner Losh]

Thierry,

	Thanks for the traces and such.  I'm happy to report that I've
recreated the problem here and I committed what I hope is a fix last
night.  It fixes me mostly (there's still some interrupt storm
messages, however).  I need to find some way to get rid of those, or
at least discover where they are coming from.  I think it is a power
up issue related to the card asserting its interrupt line
prematurely.
