[mythtv-users] Problems with ACPI shutdown and restart

[Craig Huff]

Hika,

If I understand your question, you want to know how to enable/disable the
various ACPI wakeup devices.

First, I should note that (at least for my systems) all of the wakeup
devices start out disabled on boot up.

Echoing the device name (e.g. USB0) to /proc/acpi/wakeup toggles its
enabled/disabled state.

Given the example listing from my first e-mail, the following would enable
wakeups from USB devices on USB bus 0:
        # echo USB0 > /proc/acpi/wakeup
and the following would disable both the USB0 and MMAC devices that are now
enabled:
        # echo MMAC > /proc/acpi/wakeup
        # echo USB0 > /proc/acpi/wakeup
These (AFAIK) are independent and can be done in any order.

Beware that enabling one device may enable all similar ones at the same
time.  On this mobo, for instance, enabling/disabling XVR0 also
enables/disables XVR1-3, so all of them are either enabled or disabled.  If
I enabled XVR0 and one of the others (any one), then all are disabled.

I hope this answers your question.
