Hello Troy,
it seems that you run into a race condition in our code where we thought
it can never occur. Good catch!
It looks like an event queue is destroyed while on an other CPU an interrupt
is coming in.
We will fix it soon as possible. Thanks for your help!
Regards,
Heiko

Hello Troy,
did you unload first all OpenIB modules and then the eHCA module
or the other way around?
Can you see any other message (error data) in /var/log/messages?
It looks like you unloaded the module during an interrupt came in.
Can you sent us the steps / commands you've executed when
I had unplugged, then re-plugged the cable, and then ran the following:
rmmod hcad_mod ib_mthca ib_uverbs ib_ipoib ib_sa ib_mad ib_core
