Hi, thanks a lot! I can confirm that this works also on my Thinkpad
E460. Since you can probably provide more details, could you forward
this to kernel.org?

Cheers,

Bug#944257: Confirmed, possible duplicate

[Daniel M.]

Hi,

I have exactly the same behavior on my lenovo E460 laptop. No suspend
and shutdown working since upgrade to linux 5.x.

I don't know how to get more attention to this. Can we raise the
severity or flag it?

Some more info in my earlier report #939170. Maybe even duplicate?

Cheers,
Daniel

Bug#939170: Maybe wrong package?

[Daniel M.]

Hi,

is it possible this one is reported against the wrong package? It
seems like there are a few lenovo laptop / thinkpad owners who
experience this. Is there some (pseudo)package to report this to?
Maybe it gets a bit more traction there...

Cheers,
Daniel

Bug#939170: Also with systemctl suspend

[Daniel M.]

Hi,

this also happens to me when I try systemctl suspend instead of a GUI
action. So it's not a problem of the desktop environment but of kernel
or even systemd.

Maybe something with the thinkpad kernel module?

Cheers,
Daniel

Bug#939170: linux: does not suspend completely, locks up

Source: linux
Version: 5.2.9-2
Severity: important

Dear Maintainer,

*** Reporter, please consider answering these questions, where appropriate ***

   * What led up to the situation?
   * What exactly did you do (or not do) that was effective (or
 ineffective)?
   * What was the outcome of this action?
   * What outcome did you expect instead?

*** End of the template - remove these template lines ***

Since the update from 4.19 to 5.2.9 my Lenovo Thinkpad E460 no longer suspends 
properly. If I 
close the lid or chose Suspend from the KDE launcher, the system will start to 
suspend but never 
reaches standby. Power light will blink as usual, display backlight turns off 
but keyboard LEDs 
don't turn off, fan is still active.

The system doesn't respond to Ctrl-Alt-Del or change to a Terminal. No input 
changes anything. 
Waiting (30min) doesn't help either. Rebooting to Kernel 4.19 fixes the problem 
immediatly.

Expected outcome would be a complete suspend/standby state and a complete 
recovery/powerup on
lid open or press of any key.

Bug#815037: firmware-iwlwifi: Bug also leads to kernel panic and freezes

[Daniel M.]

Bug message and freezes / panic is solved when I downgraded to stable.
So no HW problem.
