    Bug-Entry :
    Subject : scheduling while atomic: pptpgw

    Rafael, I'm not sure we need 'scheduling while atomic: pptpgw' bug.
    Initially BUG 13522 was named "BUG: scheduling while atomic: pptpgw"
    and renamed to "BUG: scheduling while atomic" since I was not sure wheter this is ppp or scheduler bug...
