Thishappens on the latest FC6 kernel 2.6.20-1.2948 and appears to be a bug in the VDK driver. Until this is further understood you can use a workaround for VDK thathas been attached to the post. It can be used with VTune 9.0 Update1 on Linux systems running kernel 2.6.20 and later (e.g., FC6 with the latest updated kernels).
Please let me know if this does not help.

Thank you for the information. It looks like the patch works not for all systems. So recommendation for nowwill beavoid running sampling on 2.6.20 kernels and possibly use 2.6.18 kernel.
