No Simultaneous Bluetooth and WIFI with 14e4:4315

It is not possible to use both bluetooth and wifi at the same time with my 14e4:4315. I can use one or the other; for example I can boot and then pair and communicate with a bluetooth device if I do not make use of the wifi (includes scannning), but if I scan or associate with an AP the bluetooth connection is immediately dropped and cannot be reestablished, and though bluetooth commands can be issue they do not appear to do anything. It is possible to maintain simultaneous connections with the wl driver. Is this a known problem?

Thanks,
Nathan
