Hello,
FYI this happens in mainline kernel 4.17.0-rc1.
It looks like a new regression.

Are you running lnet selftest ?
Perhaps yes -- it's randconfig boot test and the .config does include
CONFIG_LNET_SELFTEST:
CONFIG_LNET=y
CONFIG_LNET_MAX_PAYLOAD=1048576
==> CONFIG_LNET_SELFTEST=y
CONFIG_LNET_XPRT_IB=y
Is this a UMP setup?
Yes, .config has:
# CONFIG_SMP is not set
The reason I ask is that their is a SMP handling bug in lnet
selftest. If you look at the mailing list I pushed a SMP patch
series. Can you try that series and tell me if it works for you.
So it looks your fixup patch is not for this case? Anyway the
reproduce-* script attached in the previous email should be fairly
straightforward to try out for reproducing the bug.
Thanks,
Fengguang
