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. [2] https://thunk.org/android-xfstests Does anyone know if kernel CI is running xfstests regularly?
