Firewire cards and deep sleep, was: Re: [G4] Help! G4 price comparisons

[Andrew T. Lynch]

Hi Sean,
I have tried two different MacAlly PCI Firewire cards, and both prevent 
deep sleep with a "Deep Sleep prevented by non power managed pci 
firewire card" message in the log. One of these cards was labelled for 
Mac OS X, and the other was not.  Both worked well, with the exception 
of the sleep problem. I spoke to someone at Wiebetech when I was 
considering buying one of their cards, and came away with the 
impression that it could be my machine, rather than the card. He also 
tried to convince me that it was a bad idea to allow a machine with 
external firewire hard drives to sleep, regardless of the support 
provided by the cards.  Since all I needed was more firewire ports, I 
ended up buying an external hub, which ended the experimentation.
