Hi. Thanks to this forum
http://dug.net.pl/tekst/111/suspend___problemy_z_acpi_na_przykladzie_asus_k52jr/
there is solution. All you have to do is to make a file:
/etc/pm/sleep.d/20_custom-ehci_hcd
and add this:
!/bin/sh
# File: "/etc/pm/sleep.d/20_custom-ehci_hcd".
case "${1}" in
hibernate|suspend)
# Unbind ehci_hcd for first device 0000:00:1a.7:
echo -n "0000:00:1a.7" | tee /sys/bus/pci/drivers/ehci_hcd/unbind
# Unbind ehci_hcd for second device 0000:00:1d.7:
echo -n "0000:00:1d.7" | tee /sys/bus/pci/drivers/ehci_hcd/unbind
;;
resume|thaw)
# Bind ehci_hcd for first device 0000:00:1a.7:
echo -n "0000:00:1a.7" | tee /sys/bus/pci/drivers/ehci_hcd/bind
# Bind ehci_hcd for second device 0000:00:1d.7:
echo -n "0000:00:1d.7" | tee /sys/bus/pci/drivers/ehci_hcd/bind
