Suspected commit introducing the regression:

9710794: async: remove the temporary (2.6.29) "async is off by default" code

(i'll now try a revert of this.)

That's what I figured was the culprit as well, but that does not really
tell us anything about what part of async.c is buggy :-)

In my case, the system doesn't hang or anything, it continues to boot into a working system (except for no wireless and usb).
The only thing is that shutting down doesn't work. I have to hold the power button because it hangs on shutdown.
