Hi, I'm trying to get FreeBSD to resume properly on a Thinkpad L512. It seems that is able to go to sleep, the power button pulses slowly. The corresponding /var/log/messages entry are: Jun 23 16:57:57 thinky acpi: suspend at 20130623 16:57:57 Jun 23 16:58:01 thinky kernel: info: [drm] Resetting GPU But after I push the button again to resume, I just hear the fan goes crazy...and the CD-ROM doing something...and it just freezes in that state. I think it is very early in the process, since none of the kernel debug methods show anything. I have this in /boot/loader.conf: debug.acpi.layer="ACPI_ALL_COMPONENTS ACPI_ALL_DRIVERS" debug.acpi.level="ACPI_LV_VERBOSE" boot_verbose="YES" debug.acpi.resume_beep=1 But I hear no beep, and no other messages are printed in /var/log/messages. The next messages after the two lines above look like this: Jun 23 16:59:28 thinky syslogd: kernel boot file is /boot/kernel/kernel Jun 23 16:59:28 thinky kernel: e> port 0xcf8-0xcff on acpi0 Jun 23 16:59:28 thinky kernel: pcib0: decoding 4 range 0-0xcf7 ........ which I think are after I manually power-off and power-on the laptop. If this info helps, Ubuntu is able to suspend/resume properly. I also did a recent upgrade of BIOS. Can anyone help me make progress here ? Thank you, Stefan
