ACPI-related problem with resuming from RAM

[Rafael J. Wysocki]

Hi,

To make my box (Asus L5D, x86_64) resume from RAM, I have to unload all of the
ACPI-related modules and the ohci_hcd module before the suspend.

Also, I can't reload the ohci_hcd module after the resume, because if I try,
the system crashes with the appended trace.

Greetings,
Rafael
