I also experience this bug on karmic using an intel BCM4311 wireless card.
Same issue, the wireless connection is randomly reset every 5 - 10 minutes.
I've tried the various wireless drivers for my chipset, and all except ndiswrapper have this problem.
I also tried the upstream linux modules with the same effect.
In the system log, I get this message at the time of the reset:
