Not everyone use Fedora so providing info which kernel versions work and
which don't would help. Does Fedora usually add their own patches/hacks
to kernel or is it a stock release from kernel.org? Also have you
verified that this isn't a problem in user space, for example by
downgrading the kernel to an older version?
