Peter ... thanks for pointer. > On Fri, Feb 14, 2014 at 1:28 AM, Takashi Iwai <ti...@suse.de> wrote: > Is it a Intel+Nvidia hybrid? If so, does it happen even with > CONFIG_VGA_SWITCHEROO=n? It's not Intel+Nvidia. It's Intel Core i7-4600U 2.1 GHz, Intel HD Graphics 4400. I checked my config. CONFIG_VGA_SWITCHEROO is not set.

Interesting. Perhaps it's the USB options. I had these set to "y" CONFIG_USB_XHCI_HCD=y CONFIG_USB_EHCI_HCD=y CONFIG_USB_EHCI_ROOT_HUB_TT=y CONFIG_USB_EHCI_TT_NEWSCHED=y CONFIG_USB_EHCI_PCI=y Again, These same config works find on X230. It's very strange. The same hard disk (SSD) can suspend-to-ram on the X230 but not on the X240. The X230 has i7-3520M vs X240 i7-4600U. I've even tried with all the USB set to "n" and still couldn't S2D. May be the graphic?
