I tried hard and found another problem for you :)
With Linus's current git + CFSv4 as soon as i start a guest in VirtualBox [1],
system enters the following loop;
- Whole system freeze ~5 secs.
- System works well ~5 secs
- Whole system freeze ~5 secs.
Again mainline has no issues but its %100 reproducible under CFSv4.
Following "ps aux" and "top" outputs grabbed while system works well, i cannot
do anything else while system freezes except moving mouse for fun :P
