So were you able to reproduce this on a 5.6.0-rc1 kernel or not?
No. I don't reproduce it on 5.6.0-rc1 kernel, but 5.6.0-rc1 kernel hang on
my KVM machine when run generic/269.
I'm not able to reproduce the 5.6.0-rc1 hang using kvm-xfstests[1].
Neither has any other ext4 developers, which is why it might be useful
to see if there's something unique in your .config for 5.6.0-rc1.
Could you send us the .config you were using?
Sorry for the late reply.
my 5.6.0-rc1 config as attach.
Unfortunately, I just tried using your config with kvm-xfstests, and
it passed without problems. Did you say this was a reliable
reproducer on your system?
Yes, 100%. Tomorrow I will try it on other kvm machines.

This was run on a Debian testing system, with kvm version:
QEMU emulator version 4.2.0 (Debian 1:4.2-3)
I don't test on debian. qemu vesion as below:
# qemu-img --version

What about hardware details of your system? How many CPU's, memory,
etc.? And what sort of storage device are you using for kvm? (I'm
using virtio-scsi backed by LVM volumes for the scratch and test
partitions.)
4cpu and 4G memory(4numa node),4G swap. storge device as below(device
bus ide,storage format qcow2)
disk type='file' device='disk'>
<driver name='qemu' type='qcow2'/>
<source file='/var/lib/libvirt/images/test.qcow2'/>
<target dev='hdc' bus='ide'/>
<address type='drive' controller='0' bus='1' target='0' unit='0'/>
