Comment 31 for bug 599017

I've been trying to reproduce this on a machine with a different Intel graphics chipset, but no luck.

Let's start by trying to narrow down a bit the range for the bisection. Please test the following mainline builds, starting with v2.6.33.

http://kernel.ubuntu.com/~kernel-ppa/mainline/v2.6.33/
http://kernel.ubuntu.com/~kernel-ppa/mainline/v2.6.34-lucid/
http://kernel.ubuntu.com/~kernel-ppa/mainline/v2.6.35-maverick/

If you find the problem is not present in v2.6.33 there's no need to test .34, and if it's not present in .34 there's no need to test .35. Please report your results back here. Let me know if you need instructions on installing these builds. Thanks!
