I have seen this on the "testing" setup on the desktop here at work. I 
strongly suspect that it has something to do with acpi ordered 
power-down states. Not hibernation or suspect, but a setting which 
reduces power usage when the machine is not touched for a period of time.

And certain programs such as myth do not seem to recover gracefully. It 
may be some sort of race condition between/among the BE, FE and mysql. 
and the BE fails to record programs which it ought to have done.

I haven't spent the time to adequately determine exactly what settings. 
This does not occur on the myth box at home.

And yes, it is a big red switch recovery here too.
