Actually we are trying to read a data from the AMS2 bank2, while reading the data from the AMS2, we are facing the below cplb issue.

Let me know your suggestion to fix this issue in 2008R1
The same is working fine in 2008R1.5 release.

Senthil:
There were anomaly workarounds and many, many bug fixes that went into 2008R1.5 - in fact you should be using the tip of the branch, not the tar ball.
Upgrade.
Or - fix it yourself.
