I moved my development work to 3.3.0-rc1 from wireless-testing repository. After loading the brcmfmac driver (12 sec.) I suddenly see the BUG message 'scheduling while atomic' and it fills up the entire log with the machine becoming totally unresponsive. Any suggestions on where to start looking. What type of problems could cause this? Gr.
