Comment 1 John W. Linville 2012-01-19 16:12:17 UTC

Can you recreate this with kernel-3.1.10-1.fc16 or later?

Comment 2 Scott Howarth 2012-01-24 08:19:43 UTC

Thanks John, I'll try it out, ASAP, and get back to you.

Comment 3 Scott Howarth 2012-01-24 09:18:13 UTC

Installed kernel-3.2.1-3.fc16 and the problem didn't seem to occur.

Another WARNING did occur (net/sched/sch_generic.c:255), which I may raise in another Bugzilla.

This can be closed. Thanks
