Re: PATCH: Fixes for ide-disk.c

[Nigel Cunningham <ncunningham@clear.net.nz>]

Hi.

As far as ide code goes, I'm trying to:

1) Get rid of messages that don't need to appear during suspend (so the
'nice display' looks nice (hence printk changes)
2) Make sure the data actually does make it to disk before we poweroff
(hence write back cache interest)
3) Make sure ide_suspend/unsuspend do the right thing (however that's
defined).

I hadn't looked at the code yet to see why it's called twice - too busy
with other things. I did wonder if 

        device_suspend(4, SUSPEND_NOTIFY);
        device_suspend(4, SUSPEND_SAVE_STATE);
        device_suspend(4, SUSPEND_DISABLE);

might do it, but it's an untested theory.

Regards,

Nigel
