Seems every time that someone turns up one of the problems with this "freeze" thing, the same responses come back: "we can't fix that because we don't want to spin down drives". I've begun thinking that calls like pm_should_I_spin_down_drives() would be a better structural approach than continually redefining this "freeze" thing so it makes less and less sense to all other drivers ... who nonethless need to clutter themselves up with a growing list of special cases, to accomodate rotating media that may not even exist in the target system. > OTOH I think at least some device driver writers assume that .resume() will > always be called after .suspend() which only is true for non-modular drivers > (or for modular drivers loaded from an initrd before resume). Say what? Of _course_ resume() should only be called after suspend(). If that's not true in any case, the code wrongly issuing the resume() is buggy. I don't see where you're collecting that list of special cases. It doesn't match what I've observed ... and even if it were correct, I'd say that's yet another case where special casing reflects bugs. - Dave ------------------------------------------------------- Using Tomcat but need to do more?
