Sounds like your ISL troubles are related to BugID CSCdm12519
or BugID CSCdp55077.
I recall having an issue with older H/W revision FE PAs (1.0 or 1.1)
as well. You wouldn't happen to be using these here, would you?
As for your SMIP woes, the only way I got these interfaces to work
correctly in 12.0+ IOS code was to configure (gasp!) backing-store
transmit buffers on their respective interfaces. Kiss that RSP
performance good-bye...
