Turns out this only repreduces on nvdimm devices, xfs without dax
mount option. More logs are attached.
It's a hang, so what's the output of sysrq-w once it's hung?

Only xfs. Test on ext4 ends shortly.

Why? I thought LKML was better archived.
The lists are all archived, but that's irrelevant. The list you
should report problems to is based on the scope of the problem, not
whether the lists are archived or not.
Because the scope of the problem at this point is XFS, it's
inappropriate to report it to lists that are for general kernel or
VFS issues. There's enough noise on those lists without everyone
bombarding them with subsystem specific issues - that's why we have
subsystem specific lists in the first place.
If it turns out to be a problem in some other subsystem, we'll add
cc's to other subsystem or general lists as appropriate.
