I am trying to get oprofile running on Linux 2.6 (RedHat). Following is a
cat of /proc/cpuinfo:

When I try to do a "opcontrol --start", the kernel either hangs or crashes.
I have peppered the oprofile "driver" code with printk's to try and isolate
the problem. It is doing a bunch of default_open's and also calls to
ulong_write_file. Any ideas how I can track this problem down?
