Thank you everybody, specially Micha and Mark. OK, this almost worked. This is my setting. On a Kernel 2.6.0-test2 I have this built-inl: CONFIG_PM=y CONFIG_SOFTWARE_SUSPEND=y CONFIG_ACPI=y # CONFIG_ACPI_HT_ONLY is not set CONFIG_ACPI_BOOT=y CONFIG_ACPI_SLEEP=y CONFIG_ACPI_SLEEP_PROC_FS=y CONFIG_ACPI_AC=y CONFIG_ACPI_BATTERY=y CONFIG_ACPI_BUTTON=y CONFIG_ACPI_FAN=y CONFIG_ACPI_PROCESSOR=y CONFIG_ACPI_THERMAL=y CONFIG_ACPI_BUS=y CONFIG_ACPI_INTERPRETER=y CONFIG_ACPI_EC=y CONFIG_ACPI_POWER=y CONFIG_ACPI_PCI=y CONFIG_ACPI_SYSTEM=y
$ cat /proc/acpi/sleep gives me back: S0 S3 S4 S5 sudo echo 3 > /proc/acpi/sleep two beeps, black screen within one second, computer off... The problem is waking it up. If I hit the power button (the way I use to wake up the machine with APM/suspend and MSWindowsACPI/suspend), the screen lights up (but still is black, the fan turns on, and that's it. I have to reset computer (turn it off and reboot). sudo echo 4 > /proc/acpi/sleep Bunch of processes "entered the refrigerator" Freeing memory..... Black screen, but still powered up, then after a minute I get this text: [nosave c040a000] critical section/:done (62163 pages copied) uhci-hcd 0000:00:1d.0: Resume uhci-hcd 0000:00:1d.1: Resume eth0: Setting half-duplex based on auto-negotiated partner ability 0000 hda: wake up request initiated, waiting for !BSY hda: start_power_step (step: 1000) hda: completing PM request, Resume writting data to swap (62163 pages) And again thats it, hangs and I have to turn it off and reboot. Any ideas? PS. I do not know if acpid is running, when I try to fire it up I get this: can't open /proc/acpi/event: No such file or directory -- To UNSUBSCRIBE, email to [EMAIL PROTECTED] with a subject of "unsubscribe".
