Comment 27 for bug 952080

I suffer from the same problem on a dell studio xps 1340 laptop, 64 bit.
This problem still exists with the current upstream kernel here: http://kernel.ubuntu.com/~kernel-ppa/mainline/v3.4-rc2-precise/
In this upstream kerenel I had no support for my proprietary nvidia and for bcmwl drivers, but the problem was reproducible.
Please let me know if I can supply more data.
