svi autostate issue

We have several catalyst 6500/sup720 12.2(18)SXF17 connected to l2 ring.

All vlans bound to MST0 instance.

One of switch has ring interface in BLK state, and other ring interface  in FWD state.

Several ring vlans has L3 SVI on that switch.

According to MSTP rule, when topology change occured switch temporary  block all l2 ports.

There is no L2 port in forwarding state so it put SVIs to DOWN state.

Then it move alternate BLK port into FWD state and put all SVI to UP state.

How can i disable svi autostate feature to avoid SVI flaps?

There is no such command in native IOS.

Thank you.

svi autostate issue

I am also interested in an answer to this.  I have a 6509 running 12.2(33)SXJ2 that I would also like to disable autostate. The command "no autostate" on the SVI is not valid however.
