[firmware] XO laptops may cause conventional laptops to disconnect

[kimquirk]

Two people (Robert and Kim) have reported that their somewhat older conventional laptops disconnects and reconnects to their AP only when XO laptops are also on that AP.

This trac report is a placeholder to try to collect more information and run more specific tests to see it is reproducible.

I saw this as well, when testing OFW image installation with my WTR54GS.

This seems to be a duplicate of #4805...

Probably/possibly/maybe.

But this one we can reproduce in Cambridge and get packet captures for you, whereas #4805 is at a venue we don't have access to.

So I think I'd like to keep them separate unless/until we can verify they have the same root cause.

I've asked dilinger to work with you to get packet captures in Cambridge.

I've failed to reproduce the problem in cambridge; I *think* I saw it once, but it looks more likely that it was a crash in my laptop's ipw2200 driver. When I associated the XO with the "media lab 802.11" AP, my other laptop (an x40) was knocked offline. Running top, I saw the ipw2200 kthread consuming 100% cpu. Reloading the kernel driver fixed it.

After that I tried to trigger the problem again, but was unsuccessful.
