Anyone tried SystemTap with the latest RHEL5 Beta refresh

[Mike Mason]

Looks like he's trying to run the ioblock tapset file directly?  That won't work.  Stap ends up loading ioblock.stp twice which results in the duplicate probe errors. He needs to write a script that uses the ioblock tapset probes.
