What modules would qdisc's be dependent on? The weird thing is, netem
works on both machines... therefore I know qdisc's in general are
working. Lets just say its not working on my other machine, how do i go
about debugging it on the one machine alone?
Has the tc command been changed recently from your customized version back
to the standard release (ie yum running via cron) or your environment
path changed to
pick up the wrong tc command?
