Comment 25 for bug 708840

I got this laptop to suspend/resume by unloading the usb drivers.
Add this script to /etc/pm/sleep.d, call it something like
20_custom-ehci_hcd and make it executable:

BUSES="0000:00:1a.0 0000:00:1d.0"

case "${1}" in
hibernate|suspend)
for bus in $BUSES; do
echo -n $bus | tee /sys/bus/pci/drivers/ehci_hcd/unbind
done
;;
resume|thaw)
for bus in $BUSES; do
echo -n $bus | tee /sys/bus/pci/drivers/ehci_hcd/bind
done
;;
esac

I have not successfully been able to hibernate and resume even with Ubuntu
10.10 and the most up to date kernels. I ran the script:

apport-collect -p linux 708840

to report the current state. I was expecting to be prompted to enter what
was happening but there was no such prompt. The problem continues to be
that when I hibernate, instead of going into a low/no power state, the
computer freezes with a blank screen. No keyboard or mouse activity wake
(or even affect) the laptop. After hard rebooting, everything runs normal.
