Comment 4 for bug 429001

Ok, this warn actually is tripped due to this message below which occurs just before the stack dump. It seems to be a warning that we are taking a slow path in frace buffer insertion:

  [ 1086.779915] Delta way too big! 18446743427706068172 ts=18446744065310248178 write stamp = 637604180006

However this is actually benign, corrective action is taken and processing continues as normal. I don't think this can have been the cause of the network manager behaviour seen.

I am interested to know if you were using ftrace here.
