I've noticed problems with generic/650 for quite a while, but only when running tests on GCE (but not KVM). I noted this not when running xfstests on ext4; IIRC, it was was causing the VM to reboot when testing any file system. - Ted commit 6e7867469bd3b135125a76e633e0bb50045ccb3c Author: Theodore Ts'o Date: Fri Oct 22 23:24:31 2021 -0400 test-appliance: allow tests to be excluded based on the appliance flavor The generic/650 test causes an instant reboot on GCE, so add infrastructure to exclude a test based on the test appliance flavor (i.e., android, gce, or kvm).
