--- Comment #12 from Oleg Bulyzhin <oleg@FreeBSD.org> ---
I've got the same problem with my new dell vostro 5415. I've spent some time on
debugging, here are results:

1) this happens due to buffer overflow inside vt(4) - internal variable
vt_draw_logo_cpus gets non-zero value, this why we see those logos.

2) i'm not sure about security issues with this problem, thus i'll post mail to
secteam@ before revealing the fix.
