The numbers in dmesg
This has probably been asked before, but are the numbers on the left of the dmesg the seconds. After the decimal point are they fractions of a second?

With printk-times turned on, the system emits the timing data as a floating point number of seconds (to microsecond resolution) for the time at which the printk started. The utility program shows the time between calls, or it can show the times relative to a specific message. This makes it easier to see the timing for specific segments of kernel code.

A bit more info for you. If you use "dmesg -T" you will get time stamps in human readable format. Are you familiar with the "man" command. You can use it thus :- "man dmesg" to read the manual pages for dmesg.

THanks ArfaSmif,
I didn't think of man dmesg.
