---Problem Description---
The Ubuntu kernels currently have xmon disabled. xmon is a standard debugging interface on power platforms and is expected to be compiled in to enable for debugging. Please enable CONFIG_XMON.
 
---uname output---
Linux actg1 3.13.0-34-generic #60-Ubuntu SMP Wed Aug 13 15:45:54 UTC 2014 ppc64le ppc64le ppc64le GNU/Linux
 
Machine Type = 8247-22L 
  
---Steps to Reproduce---
Run the following command: 
echo 1 > /proc/sys/kernel/sysrq
Try to invoke xmon by inputting ctrl + o, x
System should drop into xmon, but the following message is printed instead: "[229073.090037] SysRq : This sysrq operation is disabled."
 
14.10 is also the same:

root@hatg5:~# grep XMON /boot/config-3.16.0-8-generic
# CONFIG_XMON is not set
root@hatg5:~# uname -a
Linux hatg5 3.16.0-8-generic #13-Ubuntu SMP Wed Aug 13 17:11:23 UTC 2014 ppc64le ppc64le ppc64le GNU/Linux
