DB2 10.5 un-installation Fails

AIX 7.1 on Power7 Platform.
I am doing this as root.
OK, somehow my instance is stuck and I cannot create any new instances for the 10.5 (db2icrt gets to step 2 of creation and sits. Have let it sit for 45minutes). db2ilist shows the instance, but deleting it says there is no instance. Tried to create a db2inst3, but it fails as well. So im pretty well hosed.
So my next step is to remove DB2. well, db2_deinstall -a fails with a bunch of errors.
How Can I crowbar this un-installation so I can re-install a new copy of DB2 or any better suggestions?

And which were these error? Generally it helps to describe in a little more detail and "error" is not quite as specific as "ACME Error 1234: failed to grommick the flurbishers."

If you have logs: show them.
If you got error codes: tell them.
If you got diagnostic messages: quote them

Just as a wild guess: you have seen this link and it doesn't apply to your problem, yes?

I hope this helps.
