Ah ok. It's just that I'm not that familiar with fedora's kernels naming :-)

So this looks based on a 2.6.31.1 kernel, more stable. And if it doesn't
happen with it, then it's fine.

That said, it's all about fedora based kernel so it's a bit hard to tell
if it came from fedora adds or vanilla kernel code.

I personnally can't help about Fedora kernels related problems.

Thanks.
