Subject: high load average in linux-3.6

Hi all.

After updating to linux-v3.6-rc1-315-g3c31a6e I noticed that load avg
is too high for "current" CPU usage & IO activity

Just after starting, I see next things:
1) I'v kill all processes that I "can"
iostat_min_tasks - http://pastebin.com/T59xKEy4
ps_min_tasks - http://pastebin.com/b7zVy6up
w_min_tasks - http://pastebin.com/UFFsncSn

2) After I started some processes/services (kde,nginx,mysql ...)
iostat_with_graph - http://pastebin.com/bejGneGv
ps_with_graph - http://pastebin.com/Nt9g0ynW
w_with_graph - http://pastebin.com/pYuUbyVY
( graph - with DE )

When I 3.3.0 I did not notice such situation.

I'v trying to set kernel cmd line to "i915.i915_enable_rc6=1
i915.i915_enable_fbc=1 i915.lvds_downclock=1 drm.vblankoffdelay=1"
like here https://bugs.archlinux.org/task/29850
But this doesn't helps.
