Hi,

       From: Peter Postma <peter.postma@chello.nl>
    Subject: Crash when removing cardbus card
      Date : Wed, 10 Mar 2004 12:10:29 +0100
 Message-ID: <20040310111029.GA27448@gateway.pointless.nl>

$ My laptop crashes when I remove the cardbus card:
$ 
$ tqphy0 detached
$ cardbus0: unmap mem space
$ tlp0 detached
$ uvm_fault(0xc035b680, 0xc02f3000, 0, 2) -> 0xe
$ kernel: page fault trap, code=0
$ Stopped in pid 6.1 (cardslot0) at	netbsd:pccbb_intr_disestablish+0x19:movl %eax,0x10(%edx)

I had a similar experience with rtk_cardbus.
When cardbus_intr_disestablish() has done in rtk_cardbus_disable(),
csc->sc_ih does not set NULL.So kernel panic,when card removed
after "ifconfig rtk0 up;ifconfig rtk0 down".

I think that com_cardbus has a same problem.

How about trying next patch?
I hope that it may fix your problem.

Best Regards
