[rhelv6-list] WARNING: at net/sched/sch_generic.c:261 dev_watchdog leads to unresponsive network

[Robin Price II]

I agree with Yossi here.  Bugzilla is not a support tool for Red Hat and 
I believe you would have better results opening a case.

I did find a kbase on this matter for you:

kernel: WARNING: at net/sched/sch_generic.c dev_watchdog() on RHEL6
https://access.redhat.com/kb/docs/DOC-48625

Best of luck!
