Ok, I can confirm this, I can see it on my system as well now. This started to
happen when I upgraded to the BIOS I suggested to you in comment#9, so probably
that won't solve your problem. Booting with maxcpus=1 gets rid of the issue for
me too. I will try now different BIOS versions to see which one is the latest
that works.

Meanwhile this isn't a graphics driver issue, I can see the problem even if I
don't start the graphical interface, just by trying to type something on the
text console. I notified already the core people (Mika Westerberg), he promised
to take a look at this.
