ACPI should use UTC, I did all the check suggests in the Wiki (see the
first post of this thread) and everything should be ok, my BIOS is
UTC-compatible

That's what I can remember at now:
- during the initial tests, made with some recording scheduled in ~30
minutes, everything went ok
- the day after I've scheduled 3 programs:
the first at 12.30 - BE woke up and recorded
the second at 16.30 - BE didn't wake up
the third at 19.00 - BE didn't wake up

it stopped waking up. After I woke up manually, it shuts down and later
woke up and recorded a further scheduling made for 21.30.
So, it looked like that: after the 1st wake up, it didn't scheduler
correctly anymore

- the third day, I realized there was some problems. I tried disabling
NTPD, made some early-tests and then, at 00:41 I let him shut down. I've
checked the wake-up scheduling - by logging the setwakeup.sh parameter in
mythbackend.log (see previous mail) - and it was set up for 12.30. Instead,
as said, it woke up at 10.30, telling (in the syslog) that it was 11.30,
and shutdown about 11.20.

This thing is getting me mad :)
