Apologies for top-posting.

I've made some progress with this, but as I suspected, I'm screwed on "namespace collision". I.e. I am unable to load a version of twa.ko that supports my 3ware card because a previous version of twa.ko that does not support it is already in the generic kernel. Changing the name of the loadable doesn't help, either.

It looks like I might have to make my own release, and my own ISO, using the driver source from the 3ware site.

Does anyone have an easier way of doing this?

I've already emailed Scott Long asking about the possibility of the inclusion of the new twa driver in the next FreeBSD, but I fear we're too far down the release process, so it could be a YEAR before there's a RELEASE that supports it.


You were on the right track with the emergency shell, but the "Fixit" mode
(now included on disk 1 for your convenience) gives you a lot more
flexibility (inclusion of "ls" is just the start!). Have you tried
something like this?

1) Boot to complete install CD
2) Go into "Fixit" mode (not just the emergency shell)
3) # sysctl kern.module_path="/dist/boot/kernel"
4) # kldload twa
5) # exit
6) proceed with installation

This shouldn't be necessary though, since twa is included in GENERIC for
both FreeBSD 6.1 and 6.2 (did you say what version you were trying to

Now, if your controller is too new to be included in the shipping version
of twa then that's another matter. If you have a binary kernel module that
uses a different driver name from the vendor you could use the same general
approach, but you'd want to configure your network interface and set up
your NFS mount prior to step 3, and include the appropriate NFS path in the
sysctl command in step 3.

Forgot to mention you'd also need to manually copy the vendor driver and
modify /boot/loader.conf on the newly installed system so it could actually
boot.. you could easily take care of that from the fixit mode shell after the
installation, though.
