Wireless card stopped working after a long-term high load

I have been daunted for a long time because of the following case,
wireless clients(1...6)<====> HOSTAP(v0.8.3)<=====>wired pcs
- Wireless to wired PCs, using iperf or other tcp testing tools, under heavy traffic. After a few hours(sometimes 30min, sometimes 12 hours), HOSTAP stopped working while other parts worked properly in the system. I checked it carefully, and found that no interrupts coming in. However, after the card stops working, if I call hfa384x_reset_port(disable, and enable card), interrupt comes again. And it can work properly now.
2, 3, wired pcs to wireless or both have similiar problems
- Ping test no problem(large packet 65500), it can work 2 days at least under ping test
At first , I suspect hostap driver has a problem. But I use the agere/orinoco card wiht firmware-based AP to test the same case in the same hardware platform, and it also failed. Once again, I suspect my hardware has a problem. The key problem is, after the card stopped working, how the card can work again if I disable first, then enable wireless card.
Even if I can solve the problem by using hfa384x_reset_port, where should I call it? I've tried to spawn one task to call it every 30 mininutes, but I failed.
Anybody has a similar problem? Any comment or idea will be greatly appreciated!
