I removed the GPFS packages from the node, nuked /var/mmfs and /usr/lpp 
reinstalled GPFS and that clears the issue but it is stuck again

There is a tsgskkm process running at 100%, been running 15 minutes now :-(

Before I go any further I am going to presume GPFS is fine on Zen5 CPUs?
Specifically dual EPYC 9555. The node is running 5.2.2-1
