Thanks! One more question, if I may: The kernel log says: Jun 24 03:43:06 localhost kernel: [ 1858.148661] in my_func1 where is the "localhost" from ? the "hostname" util does **not** show localhost, by amd1. I am not sure, if remember well, there were machines on which the hostname appeared instead of localhost rgs Kevin On Tue, Jun 25, 2013 at 6:07 PM, <Valdis.Kletnieks@vt.edu> wrote:

Hi, You are right, thanks! disabling CONFIG_PRINTK_TIME prevented this timestamps.
I believe they should have provide some sysfs entry for this, sorry they did not do so
Well actually, there's a boot-time cmdline parameter:
printk.time= Show timing data prefixed to each printk message line Format: <bool> (1/Y/y=enable, 0/N/n=disable)
And since the code that handles it treats it as a module parameter (even though it's always builtin), you get this for free:
% ls -l /sys/module/printk/parameters total 0 -rw-r--r--. 1 root root 4096 Jun 25 11:05 always_kmsg_dump -rw-r--r--. 1 root root 4096 Jun 25 11:05 console_suspend -rw-r--r--. 1 root root 4096 Jun 25 11:05 ignore_loglevel -rw-r--r--. 1 root root 4096 Jun 25 11:05 time
So save yourselves the embarassment of submitting a patch to add it. ;)
