that **seems** to be fixed, even if i run ACPI.

now i have

Stopping tasks:
===============================================================|
Freeing memory... done (42120 pages freed)
usbfs 2-2:1.0: no suspend?
Could not suspend device 2-2: error -16
Some devices failed to suspend
Restarting tasks... done

this was fixed by a patch Len Brown gave me privatly.
it's due to a pci-usb card.
it seems has not been applied yet.
can you notify him? he knows :)

good job.
