Sorry, I do not know. I ran into this bug today when I'm tracing a race
condition issue related qib. In order to check upstream linux-next fix
the race condition or not, I build linux-next-20150414 on two machines. Both
machines panic at modprobe ib_ipoib. Do you means I need to report a
bug? But I do not know report to who or where.

thanks
