First, I am surprised and pleased that ASRock is still issuing firmware
updates for such an old motherboard.  There was an update issued weeks
before I opened this bug report.

Firmware updated from 2.50 to 2.60.  The stated fix in the firmware
update has nothing to do with this bug - but the stated improvements are
often wildly incomplete.

*A* bug still exists, but it is not what I thought it was.

The wakealarm is not being cleared when 16.04 starts.  It is being
cleared when 14.04 (and others) stop.  "shutdown" preserves wakealarm
(hence my MthyTV setup is working well) but "reboot", and I suspect
"poweroff" clear the wakealarm, causing the apparent problem in 16.04
when I rebooted to test the new release.  I suspect that "hpet" was just
a co-incidence.

This bug report needs to be renamed, I'm just not sure what to.

Title:
  wakealarm is cleared on boot unless hpet disabled

Status in linux package in Ubuntu:
  Confirmed

Bug description:
  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.
