I'm having an unusual problem with my MythTV box. I have ACPI compiled in and working based on the information in /proc/acpi. If I power off the machine manually using the power button during boot for example, I can issue a wake-on-lan packet to power up the machine in the event that my UPS shuts it down, or the like. However, if it shuts down using the shutdown -h script to halt the machine, it doesn't respond to the packet. I've tried doing "echo 5 > /proc/acpi/sleep" to institute a sleep state but that doesn't appear to have any effect. Using 3 or 4 in that command powers off the machine hard (as I said, ACPI seems to work fine).
Has anyone seen this or know of a way to get the machine to do a soft power down and maintain the wake-on-LAN ability? Maybe there is some ACPI setting tweak I'm missing to tell it to do a soft power down when it halts?


The motherboard is an ASrock K7VT2 (VIA chipset) with a Linksys LN100TX (I think) card.
Thanks in advance,
Kevin

My asrock board did the same thing. I use a poweroff kernel now (as described here: http://mythtv.info/moin.cgi/ShutdownWakeupHowTo), but I think using the poweroff or halt -p command will work too.
