iwm load panic

[Christian Schwarz]

Any idea which revision/commit introduced this regression?

(I want to test iwm + freebsd-base-graphics on my laptop tonight and
 hence avoid crashers like this one in advance.)

@mmacy: is the revision in the current drm-next-4.6 branch of
        https://github.com/FreeBSDDesktop/freebsd-base-graphics.git

Thanks,
