I thought I'd dropped the ball completely. but I see it's a selftest
failure, I must not have selftests built in my config here, I don't do
exhaustive builds randconfig
This has also been built by Intel, but I'm assuming they missed their
selftest bits as well.
I'll revert that and resend.
Sorry for the noise. I'll add self tests to my builds here for future ones.
Dave.
