Hello,
I have a wireless lan card based on the Prism 2 chipset, branded by Corega, who are quite a big brand here in Japan. (details below)
Whenever I install the hostap driver (http://hostap.epitest.fi/), using "modprobe hostap_plx", the module loads fine, but the whole machine's sense of time gets very confused.
The problem continues even when I remove the module.
Asking on the hostap list a month or two ago brought no joy, and I can't find anyone else reporting a similar problem, so I'm wondering if it's just broken hardware.
The effect can be seen with a shell loop to call /bin/date.

For a few milliseconds around each second, the time jumps forward more than an hour, and then resets itself.
Updating the firmware on the card doesn't improve things, nor does installing the card in a different PC.
Can anyone suggest what the problem might be, or how I could debug it further?
Thanks!
Anthony
