Public bug reported: Ubuntu 11.10 and 12.4 Alpha crahes everytime when I tried to suspend (sleep) my new Sandybridge Notebook. Screen goes blank, HDD indicates activity and then everthing freezes. I have to power down the notebook (4s power button). After looking deeper into this and it look like a problem with the integrated USB3 port (propably: USB controller: ASMedia Technology Inc. ASM1042 SuperSpeed USB Host Controller) and is a bug that resides since Ubuntu 9.10!
On this page I found a perfectly working solution/workaround: http://ubuntuforums.org/showthread.php?t=1444822 post 7 & 8. /etc/pm/sleep.d/20_custom-ehci_hcd: -- #!/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.0: echo -n "0000:00:1a.0" | tee /sys/bus/pci/drivers/ehci_hcd/unbind # Unbind ehci_hcd for second device 0000:00:1d.0: echo -n "0000:00:1d.0" | tee /sys/bus/pci/drivers/ehci_hcd/unbind ;; resume|thaw) # Bind ehci_hcd for first device 0000:00:1a.0: echo -n "0000:00:1a.0" | tee /sys/bus/pci/drivers/ehci_hcd/bind # Bind ehci_hcd for second device 0000:00:1d.0: echo -n "0000:00:1d.0" | tee /sys/bus/pci/drivers/ehci_hcd/bind ;; esac -- and /etc/pm/config.d/usb3-suspend-workaround: -- #File: "/etc/pm/config.d/usb3-suspend-workaround".
