Mahmood, Can you please redo the same experiment with Flexus 4.0 (Without your code)? If the same problem exist, I will fix it. It is impossible for me to debug a code without having the code :)

Using the vverb level, I have attached the debug.out file. Some notes: 1- I have changed somethings in branchpredictor.cpp but have no problem in flexus-3.0. 2- Using the original iface messages, the last message in the debug output was <FastCacheImpl.cpp:294>. However I added an extra message after the "if" statement to check if the bug is the conditional statement or not. DBG_( Iface, Addr(aMessage.address()) ( << "Request Left Lookup... )); if (snp_lookup != NULL) { DBG_( Iface, Addr(aMessage.address()) ( << "Request Left Snoop Lookup... )); } DBG_( Iface, ( << "skipping if, exiting push" ) ); 3- In the attached log, my message is shown and that means there is something wrong with whom that call "push" function. If you search in the debug.out, you can see that "skipping if, exiting push" is shown several times (lines 67, 75, 82, 90, 99, 112, 119, 126, 133, 140) and the last time that it appear is in line 147. I will appreciate anyone who explain what is actually going on in the FastCacheImpl.cpp (push function). As far as I know, brachprediction messages should be appeared after FastCacheImpl. So I don't think my changes are the root of the problem. Thanks, // Naderan *Mahmood;
