Hi,

the hardware is laptop ThinkPad W530 with two graphics cards:
 - NVIDIA QUADRO K2000M
 - INTEL HD 4000 (i7-3630QM CPU)

When I set DISCRETE (nvidia) card to be used in BIOS and have these settings in /boot/loader.conf, then FreeBSD freezes on resume:

----------------------------------------
/boot/loader.conf
========================================
# BOOT OPTIONS | INTEL ONLY
hw.vga.textmode=0
kern.vty=vt
kern.vt.kbd_reboot=1
kern.vt.fb.default_mode="1920x1080"

# MODULES | INTEL ONLY
i915kms_load=YES

# MODULES | NVIDIA ONLY
nvidia_load=YES
========================================

... but when I disable them (#) the resume works like a charm:

----------------------------------------
/boot/loader.conf
========================================
# BOOT OPTIONS | INTEL ONLY
# hw.vga.textmode=0
# kern.vty=vt
# kern.vt.kbd_reboot=1
# kern.vt.fb.default_mode="1920x1080"

# MODULES | INTEL ONLY
# i915kms_load=YES

# MODULES | NVIDIA ONLY
nvidia_load=YES
========================================

... also, when I set graphics card to INTEL in BIOS (Integrated) and these modules are loaded the suspend/resume works ok (in other words, loaded NVIDIA binary driver does not break anything):

----------------------------------------
/boot/loader.conf
========================================
# BOOT OPTIONS | INTEL ONLY
hw.vga.textmode=0
kern.vty=vt
kern.vt.kbd_reboot=1
kern.vt.fb.default_mode="1920x1080"

# MODULES | INTEL ONLY
i915kms_load=YES

# MODULES | NVIDIA ONLY
nvidia_load=YES
========================================

It just looks like the new VT breaks that suspend/resume but that is only a wild guess.
