[Bug 2031580] Re: Running Ubuntu 22.04 on a 2016 Macbook Pro and waking from suspend is now broken after updating the intel-microcode package

[Steven Freeman]

I added GRUB_CMDLINE_LINUX_DEFAULT="dis_ucode_ldr" and rebooted and
suspend still was broken. Seems like intel-microcode was perhaps a red
herring. Wondering what I can do to further debug this since the problem
seemed to arise after an apt update && apt upgrade but I am not sure
what may have broken suspend/sleep. Perhaps the update && upgrade is a
red herring as well and merely coincidental since as I said, the other
packages that were updated would seemingly have no effect on this
behavior...

Title:
  Running Ubuntu 22.04 on a 2016 Macbook Pro and waking from suspend is
  now broken after running apt update && upgrade

Status in intel-microcode package in Ubuntu:
  Invalid

Bug description:
  Disabling Wayland partially helps but eventually will cause the
  computer to not wake up. This occurs both when closing the lid and
  when leaving the computer idle for some time.

  Description:	Ubuntu 22.04.3 LTS
  Release:	22.04

  intel-microcode:
    Installed: 3.20230808.0ubuntu0.22.04.1

  I expected resume from sleep/suspend to behave as it did prior. If I
  would open the lid or push any keys, the computer would wake up from
  sleep/suspend.

  Instead, the computer does not wake from sleep/suspend and I need to
  force the computer to shutdown using the power button and then turn it
  back on again.
