Kismet still seems to time out, i.e., it stops gathering packets, but the channel hopping still continues. The timeout is variable, but between 2 and 10-15 minutes.

I've tried the following:
1. Increase display timeout, (to over an hour) seemed to work once, I got my 10-15 minute value with a high display timeout.
2. Start associated with an AP (WPA2-PSK, my own home network). Doesn't seem to make any difference.
3. Start unassociated with any AP, also no difference.
4. Start associated with a "Dummy" IAP. Not sure if this makes a difference or not, as I did this about the same time as I increased the display timeout.

So, it looks like power management is putting the chipset into a low-power mode, but not turning it clear off. I've looked through gconf to try and find a way to change that value, but don't see anything obvious. Any suggestions for getting more time out of it?
