I'd be less optimistic. When you add a large pool of testers (F9 beta users) that all use the
same family of kernels, with more or less the same kernel patches, the same kernel config, the
same gcc version, and the same userspace, it's not surprising at all to get a huge spike of a
small set of common problems.
Does it means the kernel in general is good? No it means the Fedora Devel kernel has a few
oopsing bugs (as should be expected just before a Fedora release)
