Hi Kevin, guys. Thanks a lot, that helped! Everything comes back after resume without any problem. Network (iwi and fx drivers), USB... Even X is fine and I do not need to switch to console to bring it back. I tried suspend/resume 3 times and it worked like a charm each and every time. I added acpi_video_load="YES" to loader.conf and hw.acpi.reset_video=0 hw.syscons.sc_no_suspend_vtswitch=1 to sysctl.conf I noticed after resume dmesg spits out: acpi: suspend request ignored (not ready yet) wakeup from sleeping state (slept 00:00:19) Now even powerd works great automatically adjusting the speed of my CPU when idle on battery. The only thing that does not work properly is when hw.acpi.lid_switch_state=S3. It goes to sleep mode when I close the lid but X restarts after resume. I can live with that tho. Thanks again Kevin, you made my day!
