Hi Dimitris,

Don't worry, there is no such thing as silly questions. Someone out
there will also have the same issue, eventually. Or it might randomly
come back.

Maybe something to do with bug 2083453?

The clicking could be the ethernet device turning on and off?

If you look at journalctl -b0 or maybe -b-1 or maybe -b-2, find a boot
where it failed to suspend. Is there any errors after PM: suspend entry
(s2idle) in the logs? You can also look at /var/log/kern.log or
/var/log/syslog.

Thanks,
Matthew

Title:
  Suspend issue with AMD Ryzen 8840U CPU and kernel 6.8.0-45-generic

Status in linux package in Ubuntu:
  New

Bug description:
  I am running a new installation of Ubuntu noble 24.04 x86_64 (kernel
  6.8.0-45-generic) on a brand new Thinkpad T14 Gen 5 (AMD Ryzen 7 PRO
  8840U w/ Radeon 780M Graphics (16) @ 6.08 GHz)

  The machine does not suspend properly, which I noticed after returning
  from work with it in my backpack, taking it out and it was hot.

  While suspended the screen is in fact off, and the relevant LEDs enter
  a "breath" mode, indicating a suspended state, but there is an audible
  mechanical "tick" sound coming from the bottom, where I suppose the
  fan is located, and the laptop produces heat (gets hot if it's in a
  closed environment like my backpack)

  At first I thought it was a "lid closed" issue, but after further
  experimentation turns out that it's not a lid issue, but rather a
  suspension issue; suspending from the power button has the same result

  I could not reproduce this behaviour on Windows (I am dual booting,
  Windows Fastboot is off btw); suspending works properly; tested it, no
  "tick" sound, no heat.

  P.S. for what it's worth, my Thinkpad x13 Gen 1 on ubuntu 22, same
  kernel version on AMD Ryzen Pro 7 4750U, has no issues with suspend.

  Attaching system specs below. Please let me know what other info I
  need to provide

  Thanks.
