Comment 21 for bug 396780

Ok, thanks for trying. There was on change between 2.6.30 and 2.6.31 which touched the area which is present int the backtrace. I got test kernels on http://people.canonical.com/~smb/bug387161/ which would revert that change. If that still crashes, the best approach will be to provide precompiled bisection kernels between 2.6.30 and 2.6.31-rc1.
When you said 2.6.30 worked, was that an Ubuntu kernel or a Mainline kernel?
