Default IOCTL error?

Hi!

I wish to ask about something special in my "messages" log. I found
something like that:

I'm very curious about that "cut here" section and VFS and XFS lines. I
think that I can destruct data on my drive by some issue with IOCTL (as
usual this must be done to My PC - nothing googled).
