Description

An attempt to fix issue #11016 , as suggested by the issue author.

I didn't find any consistent way to reproduce the issue, but it manifests once in 10-15 reboots on my setup with ~80 calico interfaces. With this fix couldn't reproduce in ~35 reboots.

Below are some fragments of the debug log.
