Oops. You're right. I suck. I forgot to include any of that useful
stuff. I know better than to do that. :)

Orinoco CVS HEAD: 0.15rc1 not sure exactly when I updated probably early
this month.

That should be OK.

Linux 2.6.5 (Fedora Core 358)
It's an HP ZE5300 laptop with a built in 802.11b card, I'm not sure of
the manufacturer.

It's recognized as a PCI card.  Now I see why you cannot swap it :-)

Firmware Intersil 1.4.9 according to dmesg

There is a little chance that newer firmware would help. But you'll need the HostAP driver for that. See http://linux.junsun.net/intersil-prism/

Dmesg output is attached right after it stopped.
Ifconfig a bit before and right after it stops:

Actually, I asked for "iwconfig" output. Anyway, I see some interesting things already.

PCI cards are very sensitive to motherboard problems. It's possible that some changes in the kernel configuration (like ACPI) would fix the problem. I see some messages like "spurious 8259A interrupt: IRQ7" that possibly indicate that the support for your motherboard is far from ideal.

I also see that a lot of devices use IRQ 10. That shouldn't be a problem per se, but it may cause problems if another device on that IRQ is not working well.

I see a lot of link status messages. You have the complete collection, from 1 to 6! The messages are generated by the firmware. The numbers seem reasonable. For example, "AP Out of Range" is always followed by "AP In Range".

The problem is likely between the firmware on the card and the access point. The driver just notes the status messages.

I suggest that you try hostap driver in managed mode. If you get similar results, we'll know that the problem is not in the orinoco driver. You'll have more private options to tweak, such as antenna diversity.
