Since I got brought in mid-way through this discussion, can someone
summarize the vital details of the bughunt? What kernel version is
involved, and is this a regression? If so, what's the last version of
the kernel where you didn't have a problem on this hardware?
Can you trigger this failure reliably?
Unfortunately, while I'm regularly running xfstests on x86_64 on a
Google Compute Engine VM, I'm not doing any runs on arm64. I can
certainly build an arm-64.
There's a test-appliance designed to be run on ARM64 here[1].
[1] https://kernel.org/pub/linux/kernel/people/tytso/kvm-xfstests/xfstests-amd64.tar.xz
which is a Debian chroot, designed to be run via android-xfstests[2], but
if you unpack it, it should be possible to enter the chroot and
trigger the xfstests run manually on any arm64 system.

Does anyone know if kernel CI is running xfstests regularly?
