So it does look like something's messed up here. Before we pin this
down as a driver bug, we should double check that we are indeed opening
what we think we're opening, and try to track down why ldi_get_size is
failing. Try this:
#!/usr/sbin/dtrace -s
ldi_open_by_name:entry
{
trace(stringof(args[0]));
}
ldi_prop_exists:entry
{
trace(stringof(args[2]));
}
ldi_prop_exists:return
{
trace(arg1);
}
ldi_get_otyp:return
{
trace(arg1);
}
