Actually, it may be because of a missing bugfix, also. It may be because the F7 non-xen kernel is based on a newer upstream kernel version, or because I have missed some fix that went to the F7 non-xen kernel. On FC6, both non-xen and xen kernels come from the same source package, so this wouldn't happen on FC6. But somewhere between Fedora 6 and 7, the non-xen and xen kernels were split, because the non-xen kernel was being rebased faster than we were being able to rebase the xen patches. Being as close as possible to the non-xen kernel is one of my goals, but currently there may be some bits missing. -- Eduardo
