Unfortunately, no. It may be a problem with the T43. I did not see the
problem with my T30 which I used until March of this year. I had no need
of any PCMCIA card until recently when I needed a modem. That is when I
discovered that the T43 has only a single PC Card slot and an ExpressCard
slot. As a result, it will not support my trusty Type-III Xircom
Ethernet/modem card would not fit. So i dug out my ancient SimpleTech
28.8 card and tried it.

Other than the "pccard0: Allocation failed for cfe 32", it seemed to
work. I have no idea right now what the error might actually indicate,
though. And, that was last Thursday. That night, it would not power
down.

I left the card in place and had the same problem when I next tried to
reboot the system (to upgrade the ACPI code) on Saturday. I quickly
realized that the only thing that had changed was that the modem was
inserted. 

So i really have no idea when it started or if it is unique to this
laptop. 

Here is the CardBus boot report:
cbb0: <RF5C476 PCI-CardBus Bridge> mem 0xa8410000-0xa8410fff irq 11 at device 0.0 on pci4
cardbus0: <CardBus bus> on cbb0
pccard0: <16-bit PCCard bus> on cbb0

This is, for me, a very minor annoyance, but I did think it was worth
reporting.
