Suspending with ACPI
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,
