Results from Linaro’s test farm.

selftests ftrace failed on qemu-x86_64 and qemu-arm64. Please find the test log below.

Thanks for reporting! Can you share the kernel config which you used for this build? And the kernel is "next-20230314", is that correct?

Is this expected to fail ? Am I missing anything ?

No, it should be a bug. I would like to reproduce it.

Thank you,
