Re: IDE Power Management (Was: software suspend in 2.5.70-mm3)

Patch 2.5.70-mm3 and compile with gcc295 OK

Bare multisuer with serial console,
no modules, network, usb, acpi .....

During suspend, after a while (some dots on the console)
got the output below in an endless loop

Is there any debug or progress output in this version
and how to use?

Regards
Michael
