[Bug 2031580] Re: 6.2 kernel on Ubuntu 22.04 causes wake from suspend failures on MacBook Pro (Retina, 13-inch, Early 2015) Model Identifier: MacBookPro12, 1

[Marco Chiappero]

I am on Ubuntu 22.04.3 LTS, but tried the 6.2.0-34-generic kernel.

>From then on the PC did not fully recover from S3, and by this I mean
that while the screen stays black I can switch to a terminal with a Alt
+ F# combination and trigger a successful reboot. As far as I can see
it's not an Ubuntu specific issue, there is clearly a regression in the
upstream kernel, but it would great if we could narrow this down.

Of course, the problem disappears when reverting back to the
5.13.0-30-generic I was using before.

I will review the logs, but in the meantime I hope it helps.

Title:
  6.2 kernel on Ubuntu 22.04 causes wake from suspend failures on
  MacBook Pro (Retina, 13-inch, Early 2015) Model Identifier:
  MacBookPro12,1

Status in intel-microcode package in Ubuntu:
  Invalid
Status in linux-hwe-6.2 package in Ubuntu:
  Confirmed

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.
