Hi, My first test was with debug.acpi.resume_beep=1 in /etc/sysctl.conf and /boot/loader.conf. I didn't know which is the right file to set this, so I set it in both. No debug beep. According to this: https://wiki.freebsd.org/SuspendResumethis means that the wake up code in the kernel doesn't even begin. Anyway, I tested also with a stripped down kernel, made no difference. It had no usb, no network...I commented out everything I could. I tried another thing, which I have no idea if it makes any sense at all, or if it was correct/relevant what I was trying, but I generated an DSDT.aml file on Ubuntu, and copied to my FreeBSD system, and added this in /boot/loader.conf on FreeBSD: acpi_dsdt_load="YES" acpi_dsdt_name="/boot/DSDT.aml" Nothing changed. Still when I resume it happens the same: I hear the dvd-rom making a sound, then the fan goes crazy, no screen, no other lights, completely frozen, I have to turn-it off with a long press on the power button.
