I'll test 3.1.x though to verify that this is fixed.

I'd prefer 3.0.x for now as we have some other patchsets on production
kernels that are not yet available for 3.1.x. And this does sound like
-stable material anyway. If it's just a few commits, I could backport
and cherry-pick them. Could some point me the commits in question?

Thanks,
 Timo
