[mythtv-users] Can't get system to wake up at set time.

Thank you for the suggestion.
I take it that you mean the BIOS setting for enabling/disabling the HW alarm clock. If so, I have tried your suggestion and it didn't work for me.
Note that I had been successful getting the system to wakeup at a set time with the alarm clock enabled in the BIOS if I shutdown using the front-panel soft-power button but not if I let Fedora Core 6 shutdown the system.
I use nvram-wakeup to access /dev/nvram and /dev/rtc instead of using /proc/acpi/alarm because /proc/acpi/alarm is apparently misconfigured somewhere (dsdt? BIOS? FC6?).
If I do:
# cat /proc/acpi/alarm
I get a bogus return like:
even when I first set the alarm in the BIOS (or using nvram-wakeup).
If I set the alarm with:
# echo "2007-03-17 16:30:45" > /proc/acpi/alarm
I can get the same value back when I "cat" it, but it isn't set in the nvram if I reboot and go into the BIOS to check it.

Have you tried to disable the set HW clock setting ?
Also, if your method involves writing to /proc/acpi/alarm do you write in the right format and do your shutdown script run with the right priviliges.
I use /proc/acpi/alarm on my a8n-vm cms with the HW clock setting disabled, setting hw clock on shutdown made wake up fail occasionaly.

I am using nvram-wakeup and Suspend2 to set the wakeup time and
shutdown my Fedora Core 6 system so that it will wake up when it is
time to record a show.
The pieces work, but not together.
I can use nvram-wakeup to set the alarm clock and confirm it is set in the BIOS.
can set the alarm with nvram-wakeup and shut down the system using the
front panel "soft-off" power button and the system WILL wake up at the

I can use mythwelcome to invoke both of
However, when I do this, the system never wakes up at the time specified.
I have tried the suggested change to /etc/init.d/halt, but no improvement.
tried setting the alarm time twice with manual invocations of
nvram-wakeup (to the same time) followed by a forced shutdown (shutdown -n now), but no

The mobo is an ASUS A8N-SLI with an Athlon 64
3200+ and 512MB. I upgraded to this from a Gigabyte GA-7DX mobo I had planned to use because I had the same problem with it using FC5 and thought it was just too old/incompatible.
I would consider using a different distro, but based on Jarod Wilson's
website, I would expect that FC is suitable. I find it hard to believe
that this new ASUS mobo is incapable of supporting ACPI suspension and
wakeup by alarm clock.
I am running out of ideas.
I've been struggling with MythTV since September and just about run out of patience. If I can't get this working this month, I'll just have to give up on Linux and MythTv and go buy a Tivo because "it just works".
Any help would be appreciated.
