hostap_pci connects fine but drops all connections after a few minutes

[Brad Hein]

I'm experiencing a strange phenomenon where hostap is allowing clients to 
connect, but drops them after a period of time. During the time the client 
is connected, data transfer is good. When the client is disconnected, the 
client link goes down and the only way to re-establish it is to disable then 
re-enable the device.
The client is a Orinoco card on a Dell laptop. I've also tried a DWL-650 
linksys pcmcia card too. The client isn't the problem though, because I can 
connect to other Ap's flawlessly.

I'm looking through the logs and I see a few things that seem suspect... 
I'll paste them below. With any luck, someone can help me make sense of the 
phenomenon and help me get it working! =)

My client's MAC is a6:50:3f:73:3f:73
Here's some syslog messages:

Syslog logs a few errors right around the time that the client's link goes 
down... It's hard to pinpoint exactly where it happens, but it's somewhere 
within this glob:

I've got debugging cranked up so high I don't know what Is and is not 
relevant... Please let me know if I need to include more info...
