The interaction between ptrace and freezer is complicated (as ptrace in general),so there are known cases when spurious cgroup transitions (frozen <-> non frozen <-> frozen ) can happen.
When test ran for 8 times it got failed 5 times. I have noticed intermittent failure on x86_64, arm64 hikey device and qemu_arm64.
Oh, it wasn't nearly as bad when I ran it. I'll take a look.
Does it create any difficulties? If so, I'll send a diff to ignore the result of this test for now.
No difficulties. I will mark this test case as known failure.
