vtune_drv kernel panic

vtune_drv kernel panic

Portrait de klf@yahoo-inc.com

I am using ptu30_005_lin_intel64 on a Rhel5 2.6.18-53.1.14.el5 kernel (to support a third party driver). I built a VTune driver for this kernel, and am able to load it without problem. But running vtsarun often results in kernel panics. Below is the console message from one incident.

what kind of machine (processor in particular) are you using?

Also..do you have a copy of vtune on the machine? If you do you may have had the vtune driver loaded rather than the PTU driver. The VTune installer will configure things so the driver its driver is reloaded when you reboot..in such a case you have to invoke rmmod-vtune to remove the driver (this is in the vdk directory under both vtune and ptu) before invoking insmod-vtune in the vdk directory under the ptu tree

I think that was the problem. All is working now. Thanks.
