45b3fae4675dc1d4ee2d7aefa19d85ee4f891377 resolves the issue. The fix
was originally added to the v6.7 kernel and has been back ported to the
v6.6 kernel, but not the v6.5 kernel (yet). A quick search shows the
initial (buggy) patch only brought back to v6.5. So, this is only being
seen on nanbield.
The errors being seen are networking related. For example, on the
fvp-base machine in meta-arm, I see the following:
