Looks like I can't reproduce with rc1-git5 (after several hours)...
I'll try -git3,-git4.

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...
