Overview
dmesg is the command that prints the message buffer of the kernel. The output of this command typically contains the message produced by the device drivers. During the boot process, the kernel loads into memory and activates its device drivers, which, in turn, generated output relevant to their activity. Normally this output is generated at a speed where individual messages cannot be read by a human operator. The dmesg command allows reviewing these messages after the system has started.
