Great! I'll send it to both places since I've actually seen this
problem on both release and beta drivers.

Let me start off by saying that I actually discovered the problem while
using the Macsense AeroCard Plus drivers which I believe is repackaged
IOXperts drivers after poking around a bit. After fiding this, I
downloaded IOXpert versions of the drivers and found the same problem.
I've tried to communicate the problem to Macsense but that hasn't been
going too well.
I've been tracking the issue since OS X 10.2.6 or so with a Macsense
Aerocard Plus which is an Intersil card.
The problem is that the driver seems to have a problem reattaching to
the card after it has been ejected and reinserted. The result are
somewhat random however. Sometimes if I eject the card and reinsert it,
the driver reattaches fine (with another problem .. read on for
details). Other times it will fail to attach as shown in the kernel
messages included below.
Interesting item to note is that when I eject the card, the interface
doesn't go away (as seen by running /sbin/ifconfig). I think it's
supposed to go away when the card is ejected, correct?
If the driver doesn't reattach to the card and continually
eject/reinsert the card (in hopes of getting it to work of course
<smile>), sometimes...just sometimes .. I get a kernel panic. I can get
a kernel panic guaranteed if I attempt to reboot/shutdown after the
reattach has failed. Kernel panic log is pasted after the system.log
messages.
If the driver does happen reattach the card works fine but with some
other problems. As noted above, the interface doesn't go away when the
card is ejected. When this happens, the addresses the card was using
doesn't seem to get released either. This is probably related to the
DHCP release failure from configd in system.log. The issue is that the
card now has two addresses. One from the first time it was inserted and
requested an address and another from this time. The card is now
listening on both IP addresses. But wait there's more! If I happen to
eject the card, reinsert it, and get the driver to attach again ...
yup, it now has three addresses.
Some of these issues might be related to OS X itself. I am an ADC
member and can file a detailed bug. However, I would like to first
determine if the problem is with the drivers or PCMCIA subsystem before
doing so.
This looks like a lot of information. Let me know if anything is
unclear or if more information is needed.
