[Bug 1550839] Re: wakealarm is cleared on boot unless hpet disabled


Peter D., thank you for reporting this and helping make Ubuntu better.

As per
http://www.asrock.com/mb/AMD/970%20Pro3%20R2.0/?cat=Download&os=BIOS an
update to your computer's buggy, insecure, and outdated BIOS is
available (2.60). If you update to this following
https://help.ubuntu.com/community/BIOSUpdate does it change anything?

For more on BIOS updates and linux, please see

Please note your current BIOS is already in the Bug Description, so
posting this on the old BIOS would not be helpful.

Also, you don't have to create a new bug report.

Once the BIOS is updated, if the problem is still reproducible:
1) Please provide the output of the following terminal command (not perform an apport-collect):
sudo dmidecode -s bios-version && sudo dmidecode -s bios-release-date
2) Please make a comment specifically advising on if there was an improvement or not.
3) Please mark this report Status Confirmed.

If it's not reproducible, please mark this as Invalid.

Thank you for your understanding.

  wakealarm is cleared on boot unless hpet disabled

Status in linux package in Ubuntu:

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.
