Kubuntu edgy 6.10 on a Centrino Duo with ipw3945 wireless. Full configuration of the hardware is here: <a href="http://baheyeldin.com/click/782/5">Toshiba Satellite A100-TA6 with Kubuntu</a>.
Occasionally, when an incoming call from Skype comes in, (and perhaps when I am on battery), the machine will hang for 30 seconds or so, then everything comes back to normal.
Plain vanilla kernel, with only kqemu tainting it (and perhaps the ipw3945)
