I'm using Vtune Performance Analyzer 7.2 for Windows with Vtune RDC 3.0 for Linux. The Linuxdsitribution I used is Cent OS 4.1 which used 2.6.9-11 kernel by default.
I downloaded 2.6.13-1 kernel version andfound VTunehas some problems with this kernel version.Whenever I added L2 cache miss event to the sampling activity, both VTune performance analyzer and rdc hang up after the sampling is started. If just sampling clock ticks and retired instructions, no problem.
However, this problem doesnt exist ifthedefault kernel 2.6.9-11is used.

I haven't heard about this problem before, but let's make sure you have the latest software, which was updated around AUG 22 of this year. You can download it from Premier. Internally we call this the VDK update 1.
If you go to downloads at the premier site, I think you'll want the latest setup_rdc.tar file, which has the above date. The upgrade was designed specifically to assist our 2.6 customers.
You'll need to uninstall the older version first. Let us know once you've done that, and how it's going.
I downloaded the latest setup_rdc.tar and install it on the Linux kernel 18.104.22.168. VTune Linux RDC doesn't hang up any more. But VTune Windows performance analyzer reports "Sampling Unexpectedly Stopped" whenever L2 cache miss event is added to the sampling activity. I remember this happens before when I added L1 cache miss event.
I don't know why this happen?
