This looks all good, you are not supposed to do anything about it.

I see softint related hangs on macppc regularily, that is why I disabled
fast softints in HEAD - but that doesn't seem to fix it, only makes it
less likely.

When this lockup hits and I have top running and showing kernel threads
one of the CPUs is busy in doing something like nd6timo, or you can
get the ps output from ddb and check it there. Somehing happens while
one thread is running a softint and it never returns from there, which
totaly blocks that CPU. I think I filed a PR but never got around analyzing
further.
