Jason, myself and I am sure many others don't have any trouble upgrading a new kernel to support new hardware. I think the problem, at least from my perspective, is that there's certain amount of uncertainty of having to take code from another operating system (I realize NetBSD is very similar to FreeBSD, but they differ enough to cause problems at the kernel level) and incorporating it into FreeBSD. If you recall, your own chio code wasn't incorporated into the kernel until very recently. We've taken the similar path with chio as we did de and ultimately it just wasn't practical to track the corresponding NetBSD changes because the FreeBSD kernel changes enough on each release to break the NetBSD code. I should point out that as of today, there still isn't an "up-to-date" FreeBSD kernel that supports the 21140-AC de cards. Even the NetBSD support for it has been shoddy until about a month or so ago. Tim
