Bisecting between v6.6 and v6.7 might be the quickest way to find it,
but it's a fair bit of work on your end.
How do you trigger the problem?
It looks like you're capturing console output, and most of the kernel
messages don't appear on the console. The kernel messages (dmesg) I'm
interested in should be captured somewhere like /var/log/dmesg or
similar (I don't know the exact filename for Red Hat).
