The dmesg buffer lives in memory, so chanches this is filesystem related are slim. When booting, the contents of the existing dmesg buffer are examined. If the current contents are deemed to be a dmesg, it is not cleared. It's possible the (random) contents of the buffer are seen as valid by chance and are thus regarded as dmesg content. Reboot or other activities producing kernel output wil clear this random data and fill it with usefull data in the end. -Otto
