Bug#631945: HFSC warning issue
Oops - my logs are again filled with the WARN_ON from
net/sched/sch_hfsc.c:1427. Sorry for the confusion, it looks like
"initialize parent's cl_cfmin properly in init_vf()" is not to blame.
This is an amd64 system. Vanilla kernel.org kernel except with fglrx
(the amd/ati radeon proprietary driver - yes it is a router and an
HTPC...) loaded. I should probably start bisecting then, but it's a
little tough when it can take more than two days to trigger :(
