We're running 12.0(19)S2/S3 on our 7500s and 7206s without problems.

On the 12000s, basic IP routing (no ACLs) on 12.0(19)SX was pretty good. We're
having a lot of line card crashes and tag switching problems with 12.0(21)S2/3.
Mainly on the Engine 2, E3, and E4+ line cards.

12.0(22)S has a lot of new features from the ST series. I would recommend
caution and wait for 22S1 or 22S2.
