Comment 22 for bug 433541

I have done a few more tests on this:

Currently, my system has kernel 2.6.30-gentoo-r4 and intel video 2.8.0 and the problem can be duplicated easily. I have tried downgrading the video driver to 2.7.1 and the problem persisted. The I have tried downgrading the kernel to 2.6.30-gentoo-r1 (I kept the video driver at 2.7.1) and the problem didn't happen anymore. The I have tried upgrading the video driver back to 2.8.0 (while keeping the kernel at 2.6.30-gentoo-r1) and the problem came back. So, in order for the problem to go away, both the linux kernel and the video driver must be downgraded. According to my observations, linux kernel 2.6.30-gentoo-r1 and intel video 2.7.1 seem to be working.

I had initially reported this bug on the gentoo bugzilla:

http://bugs.gentoo.org/show_bug.cgi?id=280661

I have inquired there about the differences between the two kernel versions
