<div>Numbers in square brackets are a timestamp attached to the message, which can be useful to debug problems. Its format is [seconds.microseconds], and it begins from boot up (see (var/log/dmesg; it begins from 0.0). This timestamp is ussually appended in when 'printk( )' function is called by the kernel itself.<br>
To disable it you may alter CONFIG_PRINTK_TIME kernel variable, but i'm sure someone has another best suggest. </div>
