The machine is a fujitsu S710 laptop running: FreeBSD 10.0-CURRENT #4 r237339=e61ad3a-dirty: Sat Jun 23 17:12:58 CEST 2012 I did the tests in the following conditions: - No X loaded. Everything in console. The machine has an Intel video card, but the i915kms wasn't there. - When removing modules, I tried in single user mode. The behavior is basically the machine seems to suspend fine (I see the power led blinking) but when resuming it freezes hard. I see the disk spinning for a while and then it stops. I can't ssh to it, I can't use the keyboard at all so I can issue no command at all. I've tried stripping down the kernel (everything is out except if_ath, em and usb stack). No pccard, no sdhci, no sound, no cuse4bsd, no usb hid devices (I'm using uhidd for hid devices), no acpi_video or acpi_fujitsu there but the same result. I tried enabling debug.acpi.resume_beep=1. When doing this, the laptop beeped like crazy. With sysctl debug.acpi.suspend_bounce=1, the suspend put the screen blank, however the machine stayed alive. With acpi.reset_video I got no result. I tried using the serial console on the laptop. I saw the suspend process taking down some usb devices. Resume showed nothing on the serial console. Disabling devices in the BIOS (removing wifi, bluetooth, webcam, etc ...) didn't bring me further.
