Hi,
I've recently installed FreeBSD 8.1 on a new machine and I can't get ACPI
suspend to work, so I figured I'd check here if this is a known issue, or if
I'm just doing something wrong.
ASUS M477T/USB3 motherboard,
CPU: AMD Athlon(tm) II X4 640 Processor (3013.44-MHz K8-class CPU)
Trying to suspend/resume via ACPI. I unloaded all kernel modules I could as per
the debugging hints in the FreeBSD handbook. Tried suspend to S3 and got the
following in /var/log/messages:
Jan 21 20:03:47 burk acpi: suspend at 20110121 20:03:47
Jan 21 20:04:06 burk kernel: stray irq0
Jan 21 20:04:06 burk kernel: re0: link state changed to DOWN
Jan 21 20:04:11 burk kernel: re0: link state changed to UP
Jan 21 20:04:14 burk acpi: suspend at 20110121 20:04:14
Jan 21 20:04:16 burk kernel: acpi0: suspend request timed out, forcing sleep now
Jan 21 20:04:16 burk kernel: acpi0: suspend request ignored (not ready yet)
Jan 21 20:04:16 burk kernel: acpi0: force sleep state S3 failed
Jan 21 20:04:18 burk kernel: acpi0: suspend request ignored (not ready yet)
Jan 21 20:04:18 burk acpi: resumed at 20110121 20:04:18
But the machine was unresponsive so I have to reboot it the hard way every
time. Didn't find any other info about what went wrong.
> sysctl hw.acpi
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: NONE
hw.acpi.standby_state: S1
hw.acpi.suspend_state: S3
hw.acpi.sleep_delay: 1
hw.acpi.s4bios: 0

hw.acpi.disable_on_reboot: 0
hw.acpi.handle_reboot: 0
hw.acpi.reset_video: 0
hw.acpi.cpu.cx_lowest: C1
I didn't include a full dmesg, but if it can help find the problem, I can
produce one.
TIA,
Chris
