High load which eventually leads to lockup

[Joakim Tjernlund]

The last week I have had 4 lockups which required power on/off.
Before getting there I noticed that the machine was getting slow.

top reported high load(5-10) but there was no process consuming CPU except
for migration/0 which were spicing 100% on and off. 
Ping times went up with a factor of 40 too.

Eventually I got a few entries in the kernel log:

First I was running kernel 3.9.5, then 3.9.11 and now I am at 3.10.7
running up to date gentoo, gnome2 and I have 2 monitors. 
Got no idea where this is coming from.
