UEFI wakealarm

[blind Pete]

Hi *, 

I tried posting this in nntp://alt.os.linux.ubuntu, but I did not 
get much joy, so I am trying here.  

This might be a kernel problem, an Ubuntu problem, a firmware problem, 
a MythTV problem, or a whole bunch of problems.  My Mythbuntu 14.04 LTS 
does not go to sleep and wake itself up like I want it to.  What I want 
to find out is, which of the following are real bugs and who should they 
be reported to?  

The UEFI firmware has the real time clock set to UTC.  When it was 
configured to wake at a particular time of day, it worked as expected.  
It is now configured to wake "by OS", that sometimes works.  

There is a file /etc/init/hwclock.conf that never seems to get executed.  
I've added commands to echo information to a log file, but nothing 
appears in the log file.  That file, hwclock.conf, still exists in Xenial.  

There is a file /etc/init/hwclock-save.conf that does get executed, 
but only to the line that starts with "exec".  Log entries appear up to 
that line but not after.  Deleting the "exec" and calling "hwclock" 
directly seems to work; stuff gets logged before and after that line 
and sometimes the wake alarm works.  

Sometimes "cat /sys/class/rtc/rtc0/wakealarm" agrees with 
"cat proc/driver/rtc" (allowing for timezones), but often the 
wakealarm is empty.  

Usually, "date -d +10min +%s > /sys/class/rtc/rtc0/wakealarm" 
as root works, but not always.  The wakealarm can remain empty.  

Plus a lot of things that seem to be MythTV specific, but I will ask 
elsewhere about those.
