>Description:
When a Option Globetrotter GT 3G QUAD (Also known as Vodafone 3G card) is inserted into a NetBSD-system with ohci* at cardbus? enabled, the system will freeze. The following is printed by the kernel before hanging:

cbb0: wait took 0.018532s
ohci0 at cardbus0 function 0: NEC USB Host Controller (rev.0x43)
ohci0: interrupting at 5
ohci0: OHCI version 1.0

If the card is removed again, the kernel outputs the following message and enters debug-mode.

ohci0: reset timeout
ohci0: init failed, error=13

uvm_fault(0xc084b8c0, 0, 0, 1) -> 0xe
kernel: supervisor trap page fault, code=0
Stopped in pid 9.1 (cardslot0) at      netbsd:powerhook_disestablish+0x9: movl 0(%ecx),%edx

The topic has been touched before in the mailinglists, here:
http://mail-index.netbsd.org/current-users/2005/05/10/0008.html

And there is also some information available (from the same author) here:
http://www.rinta-aho.org/docs/option3g/option.html
>How-To-Repeat:
Use GENERIC 3.0RC3 kernel configuration, enable ohci* at cardbus:

ohci*   at cardbus? dev ? function ?    # Open Host Controller

Compile and reboot.

Insert Option Globetrotter GT 3G QUAD PCMCIA card and kernel will output:

cbb0: wait took 0.018532s
ohci0 at cardbus0 function 0: NEC USB Host Controller (rev.0x43)
ohci0: interrupting at 5
ohci0: OHCI version 1.0

And the system will freeze and stay in this state forever.
