	i have a dell insprion 8500 laptop that is not very happy with my
	(dell rebadged!) ex @ cardbus cards (i have 575C and 575B models,
	both exhibit the same problems.)  it hang hard and i have to
	power cycle.  i've seen this problem ever since i got the i8500 a
	couple of months.  enabling cardbus debug shows that it hangs
	extremely early in the "insert card" event handler.  as it hangs
	even breaking to DDB there is very little else to say.

	in an i3500 the card probes like:

	ex0 at cardbus0 dev 0 function 0: 3Com 3c575CT Ethernet
	ex0: MAC address 00:50:da:30:6c:b3
	tqphy0 at ex0 phy 0: 78Q2120 10/100 media interface, rev. 11
	tqphy0: 10baseT, 10baseT-FDX, 100baseTX, 100baseTX-FDX, auto

	the cardbus driver on the i8500 looks like:

	cbb0 at pci2 dev 1 function 0: Texas Instruments PCI4510 PCI-CardBus Bridge w/ OHCI IEEE 1394 Controller (rev. 0x02)
	cbb0: interrupting at irq 11
	cardslot0 at cbb0 slot 0 flags 0
	cardbus0 at cardslot0: bus 0 device 0
	pcmcia0 at cardslot0


	insert an ex @ cardbus card into an inspiron 8500.
