I found this thread about the issue: = https://lists.freebsd.org/pipermail/freebsd-emulation/2014-August/011767.h= tml What I don't understand is why it is expected that the repository kernel = module wouldn't be in sync with the 9.3-RELEASE kernel. Is it because = the packages are relevant to all 9.x releases and there's no way to have = a kernel module work with them all? If so, why bother having a kmod = package at all? On a related note, how difficult is it to build the kernel module? I = have never built it from source in the past and don't even have kernel = sources installed. I use stock kernels from the releases. Are there = ways this build can get screwed up if options/packages aren't correct? Rob=
