But I guess it doesn't do what you expect, although I still didn't get why you want to do this.
Most of the time, if your system become unstable due to the CPU, it's an issue of temperature.
This is multiprocessor machine working in cluster. In /var/log/messages I have found this
kernel: BUG: soft lockup - CPU#15 stuck for 10s!
I would like to analyse this problem (if its possible ofcourse) with some CPU diagnostic tools, but only from RedHat repository. In the cluster node You shouldnt install not certified software. I cant stop this machine because one processor is still productive.
So, does anybody knows CPU diagnostic tool from RedHat ?
