There should be no reasons that the OE build wouldn't work. Did you do any bitbaking before you changed the MACHINE setting? Also, have you tweaked any of the MACHINE_FEATURES options (sounds like you haven't, but never hurts to ask)? I'd still try a prebuilt image just to eliminate possibilities. Otherwise you could start with making sure only modules you need are getting loaded, etc. Also, back when that atomic scheduling bug was 'normal' wifi would still work just fine, you'd just see the kernel oops at boot time and when you shutdown. Not pretty, but you might check just to be sure. If your AP is setup to be open and whatnot it should 'just work'...
