Suspend wakeup problem with Thinkpad Yoga 460

Hello,

I have a problem with my Thinkpad Yoga 460 laptop.

Screen doesn't turn on when I try to wake laptop from suspend. Just stays gray.

I have installed all the latest updatest, problem just started couple of days ago.

What could be the problem? How to fix it?

What DE are you using?

Xfce.

I used to not update my system every day and never had that problem.  Then last week i thought to freshen up my laptop and reinstalled everything and started downloading all the updates every other day and just yesterday discovered that it doesn't come out of suspend any more, although system is up to date and  it used to work fine for years.

Any ideas?

Re: Suspend wakeup problem with Thinkpad Yoga 460

Hi,
I have the same problem with suspend to ram since a few months.
Sometimes (~50% chance) my laptop freeze while resumeing from suspend to disk.
So at least after 3rd or 4th time suspending, the computer gets stuck and it has to be rebooted hard.
I suspect it to be a low level problem concluding the debugging I did.

I'm running an updated Arch Linux since 4 Years on my Lenovo Yoga 460. The disk layout is LVM on dm-crypt. Partitions (/home, /) are formated using btrfs.
Since a while I use a SD-card to upgrade my space a bit. This sd-card is also encrypted and automatically decrypted and mounted using crypttab and fstab.

The problem persists if I suspend from comandline (systemd suspend)
Further I tried to disable NetworkManager, the SD-card setup and the X-server (systemd isolate multi-user.target).
That's why I suspect the problem to be a kernel problem.

I followed some of the debugging tool from here: https://01.org/blogs/rzhang/2015/best-p … ate-issues
I couldn't find any errormessage, which give a hint of the source of the problem.
So I set initcall_debug, no_console_suspend, ignore_loglevel. To get more verbose log.

Dynamic debug is kind of not giving more information as well.

# journalctl -b -1 gives for the suspend: https://pastebin.com/DjraquCE

Now with all the log setup the last logs look like this:

What do you mean by pacman -Q: https://pastebin.com/RutNghuk

I freshly setup a new arch, with a similar encrypted /home. But the problem persists.
Does anyone still has the same problem?
