Hi,
I was trying to play with the numtasks controller.
When I try to change the sys_total_tasks parameter, the system completely hangs
after the echo command.
[EMAIL PROTECTED] ckrm]# pwd
/config/ckrm
[EMAIL PROTECTED] ckrm]#cat config
res=numtasks,sys_total_tasks=unlimited,forkrate=unlimited,forkrate_interval=1
[EMAIL PROTECTED] ckrm]#
[EMAIL PROTECTED] ckrm]# echo "res=numtasks,sys_total_tasks=10000" > config
This happens whenever I try the above.
I have used ckrm-f0.4-2614-single.patch + cpurc-v0.3-2614.
Could anybody clarify where I am going wrong ?
Thank you for reporting a new bug. The following patch fix the problem.

Chandra, Could you apply this patch to your tree?
Also the config file does not contain the details of CPU resource controller.
But the shares file contains both.
It is intentional. Since CPU resource controller _for f-series_
doesn't need any configuration parameters so far, it doesn't
need to make an entry in the config file.
Thanks,
MAEDA Naoaki
