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:
