Identified this issue in Focal starting with the update to 105 kernel. Constant soft lockups then freezing when kauditd/auditd exceeded backlog limit. Due to DoD requirements, all systems set to audit=1 in kernel boot options and have stringent list of syscalls/binaries/files that are audited.
Added focal-proposed repo and updated to 109 kernel. Few hours of compiling and heavy static code analysis loads on system and no lockups as of yet.
This is a really scary bug - seems to be present on all linux kernels and a huge threat as a DDoS.
