Not sure if this really matters and on what end the problem might be, but resuming from S3 in qemu is stuck forever here: #3 x86emu_exec_one_byte (emu=0xffffffff81eac618 <x86bios_emu>) at /usr/devel/git/cpu-pause/sys/contrib/x86emu/x86emu.c:4655 #4 0xffffffff8106c398 in x86emu_exec (emu=0xffffffff81eac618 <x86bios_emu>) at /usr/devel/git/cpu-pause/sys/contrib/x86emu/x86emu.c:246 #5 0xffffffff8106b8d4 in x86bios_intr (regs=0xfffffe002e1933f0, intno=16) at /usr/devel/git/cpu-pause/sys/compat/x86bios/x86bios.c:634 #6 0xffffffff80fb7cd2 in vesa_bios_save_restore (code=2, p=0xfffff8000365e004) at /usr/devel/git/cpu-pause/sys/dev/fb/vesa.c:551 #7 vesa_load_state (adp=<optimized out>, p=<optimized out>) at /usr/devel/git/cpu-pause/sys/dev/fb/vesa.c:1535 #8 0xffffffff810632e0 in vga_resume (dev=0xfffff800039eb100) at /usr/devel/git/cpu-pause/sys/isa/vga_isa.c:112 #9 0xffffffff8106311e in isavga_resume (dev=0xfffff800039eb100) at /usr/devel/git/cpu-pause/sys/isa/vga_isa.c:243 #10 0xffffffff80ac2de4 in DEVICE_RESUME (dev=<optimized out>) at ./device_if.h:305 ... Using -vga none works around the problem, of course. Maybe it's buggy video BIOS in the emulation. -- Andriy Gapon
