I installed CodeAnalyst 3.3 on a Quad-core 9350e Phenom with Ubuntu 11.10, kernel version 3.0.0. I did the installation form source (not the Debian package). The installation seemed to go seamlessly. However, when I try to run any type of IBS profiling through CodeAnalyst, I get the message "Oprofile driver does not support IBS profiling". When I use opcontrol to run an IBS profile, I get the message "No kernel support for IBS profiling". My understanding was that Phenom is 10h and hence supports IBS.
