I'm having problems suspending an Intel D845PESV based machine using ACPI. First, trying the following, the system will go to sleep and wake up immediately.
$ echo standby > /sys/power/state The kernel log tells me that mysqld couldn't be stopped. So, when I stop mysqld manually and unload modules uhci_hcd and ehci_hcd, I can get the machine to 'standby' state but 'mem' and 'disk' have no effect. Is there a bug in the motherboard's ACPI system or am I forgetting something? I'm using a standard 2.6.8-2-686 kernel with ACPI enabled at boot. I included some debugging information below. Thanks, -Matti $ cat /sys/power/state standby mem disk $ cat /proc/acpi/info version: 20040326 $ dmesg | grep -i acpi BIOS-e820: 000000001ff40000 - 000000001ff50000 (ACPI data) BIOS-e820: 000000001ff50000 - 0000000020000000 (ACPI NVS) ACPI: RSDP (v000 ACPIAM ) @ 0x000f70c0 ACPI: RSDT (v001 INTEL D845PESV 0x20021020 MSFT 0x00000097) @ 0x1ff40000 ACPI: FADT (v002 INTEL D845PESV 0x20021020 MSFT 0x00000097) @ 0x1ff40200 ACPI: MADT (v001 INTEL D845PESV 0x20021020 MSFT 0x00000097) @ 0x1ff40300 ACPI: ASF!
