After I installed XEN hypervisor, the tty0 (CTRL+ALT+F1) prints “powernow-k8 transition frequency failed” to STDOUT continously, how to solve it?
sudo rmmod powernow_k8
How to make the settings persistent (take effect after reboot)?
1, Create script file ‘/etc/init.d/stop_pwoerk8.sh’ as follows.
harry2vera@node1:/etc/init.d$ cat stop_pwoerk8.sh #! /bin/sh rmmod powernow_k8
2, Add the full PATH of it into ‘/etc/rc.local’ file as follows.
harry2vera@node1:/etc/init.d$ cat /etc/rc.local #!/bin/sh -e # # rc.local # # This script is executed at the end of each multiuser runlevel. # Make sure that the script will "exit 0" on success or any other # value on error. # # In order to enable or disable this script just change the execution # bits. # # By default this script does nothing. /etc/init.d/stop_pwoerk8.sh exit 0
NOTE: I tested above solution on debian Wheezy.
