Subject: A Bug in 3.9.8

Folks:

I sent the indented text to gregkh@...uxfoundation.org, inappropriately 
as I suspected. I got a polite automated response suggesting alternate 
destinations for my email. To my non-technical eyes, your addresses 
seemed most appropriate.

     "Mr. Kroah-Hartman,

     "Excuse me for bothering you, but I do not know where to report my 
problem and I found your name in 
http://kernel.ubuntu.com/~kernel-ppa/mainline/v3.9.8-saucy/BUILD.LOG.

     "I am running Linux Mint KDE v15, but I like to run the latest 
kernel. I have never had a problem before installing the latest "general 
release" kernel from http://kernel.ubuntu.com/~kernel-ppa/mainline/ 
until yesterday.

     "After I installed v3.9.8-saucy, the system could no longer "read" 
cpu usage of my quad-core Intel  q6600. Conky, "top", "mpstat -P ALL" 
all show ZERO CPU usage. Everything else is fine; it is just the 
reporting that is busted.

     "If you are the wrong person and cannot forward to correct 
destination, then I am sorry for wasting your time."

I neglected to write that when I rebooted the identical system using 
v3.9.7-saucy as the kernel, the CPU usage for each core was registering 
non-zero values when appropriate as usual.

Cordially,
Richard Corbin
