Hello, Roland!
The following was noted by Eli Cohen:

It seems that ipoib_flush_paths can be called while completions are
still
outstanding on IPoIB QP (e.g. from ipoib_ib_dev_flush). If this happens,
an
address handle might get freed while a work request is still outstanding
for it.
This can trigger a local QP error, and IPoIB will stop working, until QP
is reset.

Please comment.
