Upon further investigation, it would appear this is quite a widespread 
issue caused by a bug in the RHEL kernel-4.18.0-425.3.1.el8.x86_64.

As per the excellent Red Hat solution article, we will need to rebuild 
any packages that use the affected 'pv_lock_ops' symbol against the 
latest (bug-free) RHEL 8.7 kernel, as we have done for kmod-wireguard above.

We are in the process of identifying all packages that use the affected 
'pv_lock_ops' kernel symbol and will try to get these rebuilt, tested 
and released as quickly as possible over the next couple days.
