PAX Service Hangs System During insmod-sep3 Invocation
I am running VTune Amplifier XE (Update 4) on RHEL 5.6 (kernel 2.6.18-274.el5xen) Nehalem family processor. I am able to run the VTune analysis that does not require the PAX kernel module to be loaded. There is not a pre-built driver for my kernel version so I built one using build-driver, accepting all the defaults. This built the module sep3_4-x32_64-2.6.18-274.el5xensmp.ko. When I try to run the insmod-sep3 script it hangs the entire system before it completes. The output from this script is below:
# ./insmod-sep3 -g vtune
Checking for PMU arbitration service (PAX) ... not detected.
VTune drivers (sep3& pax)can be installed successfully on XEN Linux* OS, but hardware event-based sampling data collectionsare not supported since the tool cannot access PMU hardware resource on XEN Linux* OS. However user-modesampling data collection still can work on XEN Linux* OS.
