This may fix the issue: https://lkml.org/lkml/2018/2/13/668
Kirill posted a v2 patchset 3 days ago and I suppose the patchset should
include the fix.

Thanks for the link. I bisected based on the latest next kernel including
v2 of the patchset (IOW - the potential fix is included already).
So it seems that the proposed fix fixes certain scenarios but not all.

Are you sure? b91993a87aff is the old patch-set - which I just removed from -next
and which should thus be gone in the Monday iteration of -next.
I have not merged v2 in -tip yet, did it get applied via some other tree?
Thanks,
Ingo

I wanted to apply the fix mentioned in the link but found that the statement was movq already.
Therefore my (most likely false) understanding that it's v2.
I'll re-test once v2 is out and let you know.

movq fix is unrelated to the problem.

Thanks for testing!
Ingo, is there anything else I need to do for the patchset to be applied?
