The warning above is what kicked the "W" taint:

static void idr_remove_warning(int id)
{
        WARN(1, "idr_remove called for id=%d which is not allocated.\n", id);
}

Yes, this can happen without proprietary stuff.  The issue is that it looks like
something that is using the idr allocation scheme is busted.  Any chance you
have a better log than the snippet you posted above (ie, dmesg?)

You should open up a BZ.
