Comment 3 for bug 39338

Mine does the same thing (and did so under Breezy). It seems to happen more often (although I think i've seen it do it on its own) when the interface is in promiscuous mode, for example when using Airsnort or similar utilities. My laptop uses an Intersil Corporation Prism 2.5 Wavelan chipset, with the orinoco_pci / hermes driver. It's happened with a variety of different kernels. I doubt the problem is specific to Ubuntu though.
