Comment 66 for bug 475429

I rebuild the kernel with debug enabled.
And I tried to investigate the freeze problem.
But, kernel configuration(attached with this post) works fine.
I couldn't reproduce the problem with the kernel.
There might be some problems with lock sequence of the intel driver.

configuration change:
cpu arch -> atom ( still freeze with this change )
debug feature show in below is enabled.
