In my FVP VM, this test gets a GCS SIGSEGV before running the first test:

Do you have THP enabled? That still doesn't work (I'm expecting it to be fixed with -rc1).

I did have it enabled. After turning it off in the kernel config, the test does pass. But I see 30 lines of "INVALID GCS" in dmesg while running it. Is it expected?
