It was in my TODO list, but I am glad that you finished it :-)

Any how with this patch on my 64 bit AMD box I am getting:

[jaswinder@hpdv5 perfcounters]$ ./perfstat -e 0,1,2,3 ls > /dev/null 

 Performance counter stats for 'ls':

perfstat: perfstat.c:415: main: Assertion `res == sizeof(single_count)'
failed.
Aborted
[jaswinder@hpdv5 perfcounters]$ 

[root@hpdv5 perfcounters]# ./kerneltop 
KernelTop refresh period: 2 seconds
kerneltop: kerneltop.c:883: main: Assertion `res == sizeof(ip)' failed.
Aborted
[root@hpdv5 perfcounters]#

Thanks,
