Re: panic on pccard insert (more debug info)

I tuned on some debug sysctls, here is the result.
cbb0: card inserted: event=0x00000000, state=30000810
pccard0: chip_socket_enable
cbb_pcic_socket_enable:
cbb0: cbb_power: 3V
pccard0: read_cis
cis mem map ce6e1000
pccard0: CIS tuple chain:
CISTPL_NONE
  00
CISTPL_NONE
  00
[....]
CISTPL_CHECKSUM too short 0
  10 00
CISTPL_NONE
  00
CISTPL_NONE
  00
[and it continues like this until the panic]
