Public bug reported: When suspending this Lenovo U300s, it does not suspend. Specifically, it seems to never enter the suspend state at all; the screen goes black, but it is a lit-up black (not a turned-off-screen black) and the laptop never enters suspend. I have to kill power to get it back.
I tried the RTC clock debugging trick from https://wiki.ubuntu.com/DebuggingKernelSuspend but I think it didn't work because the laptop never enters suspend; the dmesg log after rebooting had a magic number but no hash matches.
