I'm prefacing my question with email to the FreeBSD ACPI list as this problem is to ultimately debug an ACPI problem in FreeBSD. -- START FreeBSD Email -- I'm trying to get my desktop to STR (S3) and can't even get S3 to semi-powered down state. 6.1-RELEASE-p1 I've updated the BIOS to the latest version. When I do an acpiconf -s 3 the suspend get all the way into the AcpiEnterSleepState function and begins to write registers. The last line I see (with full ACPI debugging enabled): heregs-0708 HwRegisterWrite : ----Entry Then the power light on the case starts to blink seeming to indicate that it is in suspend, except I can still see output on the monitor and the fans and harddrives are still running. Then when I press the power button to try to bring the system back up it then displays: heregs-0708 HwRegisterWrite : ----Exit and then continues with a few more HwRegisterWrite and then exits the AcpiEnterSleepState function and then does nothing. The system shows no life of coming back. I then need to perform a cold boot, because if I just hit the reset button the system doesn't restart to the point where it gets to the BIOS screen. My acpidump output is at: http://am-productions.biz/docs/bigguy.asl I've fixed the errors in the asl and tried using that, but it showed the same problem. http://am-productions.biz/docs/bigguy-fix.asl dmesg: http://am-productions.biz/docs/bigguy.dmesg When I do an "acpidump -dt" I see the following message displayed: acpidump: RSDT entry 2 (sig OEMB) is corrupt Windows isn't installed on this system so I can't compare it with that. I tried suspending with Knoppix (2006-06-01) and that worked a bit better. It successfully shuts off the disks on suspend, but the case fans and video card/monitor were still on. When you press the power button again in knoppix it successfully brought the system back to life. Getting it to the point of Knoppix would be a good start. S1 in FreeBSD does work, but it doesn't shut anything down, so it's not really useful. hw.acpi.supported_sleep_state: S1 S3 S4 S5 hw.acpi.power_button_state: S5 hw.acpi.sleep_button_state: S1 hw.acpi.lid_switch_state: S3 hw.acpi.standby_state: S1 hw.acpi.suspend_state: S3 hw.acpi.sleep_delay: 5 hw.acpi.s4bios: 0 hw.acpi.verbose: 1 hw.acpi.reset_video: 0 hw.acpi.cpu.cx_supported: C1/0 hw.acpi.cpu.cx_lowest: C1 hw.acpi.cpu.cx_usage: 100.00% debug.acpi.acpi_ca_version: 0x20041119 I've also tried CURRENT with ACPI-CA 20051021 with the same results. -- END FreeBSD Email -- Now for the Linux part. Since Linux (Knoppix with kernel 2.6.17) seems to get at least some of the suspend/resume right I'm trying to figure out how to get it to display the full debug information to compare with FreeBSD. I'm looking for how to do the following in Linux: http://www.freebsd.org/doc/en_US.ISO8859-1/books/handbook/acpi-debug.html Specifically the ACPI layer and level debugging mention at the end of the page.
