Subject[PROBLEM] Softirq ticks are incorrectly reported in /proc/stat
From
Hi All,

I am trying to run some ethernet stress tests on 3.12-rc7 and found that
the softirq ticks are being reported incorrectly in /proc/stat
This issue does not occur if I pass 'nohz=off' as the bootarg.
I have attached both the outputs (with the same load conditions).

The difference in the softirq values for CPU3 is noticeable.

Thanks.
Riyaz


Here is the output in tickless mode
