Ah, this is a different panic than I've seeing on are removal.  Looks
like a resource conflict (likely unrelated to the resources not
released, but there is a chance).

The 16-bit support is still somewhat fragile in -current...

*ALL* cards panic on reinsertion.  At least all of them that I've
tried.  This has been broken in the past 2 or 3 weeks.

Aironet/NEWCARD reinsertion panic

[Jose Gabriel J Marcelino]

Hi again,

Ok, some people tried to help me find out why does the Aironet driver
panic on reinsertion, under NEWCARD with my recent patch (see previous 
message and PR) however I need additional help to find the problem.

I'm including the complete details on the events leading to the panic.

My kernel conf is at:
http://devils.maquina.com/~gabriel/MINIME

Verbose kernel boot dmesgs are at:
http://devils.maquina.com/~gabriel/boot.newcard

Card attach messages are at:
http://devils.maquina.com/~gabriel/boot.an

The debug dmesg I get on NEWCARD after removing the card:

pccard1: 00 CD 3b
cardbus0: Detaching card: no cards to detach!
pccbb_pcic_socket_disable
pccbb0: pccbb_power: CARD_VCC_0V and CARD_VPP_0V [44]
pccbb0: WARNING: Resource left allocated!  This is a bug... (rid=0, type=3, 
addr=44001000)
pccbb0: WARNING: Resource left allocated!  This is a bug... (rid=0, type=1, addr=b)
pccbb0: WARNING: Resource left allocated!  This is a bug... (rid=0, type=4, addr=100)

This is suspicious, however I'm not sure where's the problem.
After that, after I reinsert the card I get lots of scrolling lines like this: 

CISTPL_NONE
 00

And after that DDB takes over:
