Public bug reported:
Wiley Werewolf 15.10 and Xenial Xerus 16.04 (alpha) clear
/sys/class/rtc/rtc0/wakealarm during the bootup process, unless
"hpet=disable" is given as a boot parameter. (Tested on Xenia, not
tested on Wiley.)
Trusty Tahr 14.04 is well behaved, without the hpet parameter.
Background; the main installation runs MythTV which sets and uses the
wake alarm. A test boot into a newer OS clears the alarm and MythTV on
Trusty does not wake up to record the next scheduled TV program.
