Hi .

"unregister_netdevice: waiting for ppp0 to become free. Usage count = 1"

I'm having a truckload of these messages when my ppp connection dies and
I try to relaunch it.
ifconfig ppp0 hangs in D state, pppd too.

I'm using QOS (wondershaper) with cqb qdisc, and apparently, this is
the culprit.
after a quick search, it seems cqb doesn't update refcount on unload.
There is a patch that seems to solve the problem :
