udev load cpu too much

[A.Burinskiy]

Hi,

I have Dell Studio 1737 install ubuntu 64. udev spontaneously starts 
load cpu, for sure after suspend, but not immediately. Problem 
disapeares if udevadm control --stop-exec-queue issued. But that is not 
correct solution.

udevadm monitor --env

UDEV  [1263527709.801081] change   
/devices/pci0000:00/0000:00:02.0/drm/card0 (drm)

Digging the internet I found that most likely the problem caused by 
xserver-xorg-video-intel dirver. There were some patches to the kernel 
driver proposed.

Thanks,
