[Bug 2115854] Re: The system didn’t go into suspend and got stuck

[Kevin Yeh]

Based on intel's feedback, they claimed that they tested -65 kernel and didn't see any issue with any version of intel-microcode.
On our side, I tested both -65 and -72, the issue still persists.

Bug description:
  [Summary]

  During the SRU testing, I found there are many "workstation" machines didn't go into suspend.
  After executing systemctl suspend, I can see the screen was off, but the power led didn't shows a breathing LED, then the system got stuck, only way to recover it was by power cycling.

  After power cycling I used "journalctl -b -1" to see the previous log
  and saw following log.

  Jul 03 06:58:18 ubuntu /usr/libexec/gdm-x-session[1314]: (II) systemd-logind: got pause for 13:66

  [Expected result]

  The system should wake up by pressing the power button or by rtc
  wakeup event.

  [Actual result]

  The system got stuck.
