Bios Upgrade from DMCN32WW to DMCN34WW does not support kernel 5.9, works with 5.4 in Ubuntu

[ko-christ]

In https://forums.lenovo.com/t5/Lenovo-Yoga-Series-Notebooks/Yoga-Slim-7-BIOS-update-to-DMCN34WW-breaks-option-Secure-Boot-No/m-p/5046311?page=1#5196561 it was reported that the upgrade with 5.9 is not possible because the kernel is unsigned and it fails to boot. So I thought it would make sense to try with a signed kernel.

Here is what I tried.

While I was in DMCN32WW I installed a self-signed 5.9.12 kernel and then I enabled Secure Boot.
With this setup (DMCN32WW + Secure Boot on) I was also able to boot with my self-signed kernel as well as with the 5.4.0 Ubuntu kernel but I was not able to boot with the unsigned 5.9.12 kernel which was kind of expected.

I then installed DMCN34WW but unfortunately the system didn't boot with the self-signed 5.9.12 kernel.
The system freezes with a message Loading ramdisk and nothing happens.
The unsigned 5.9.12 kernel was raising another error for the unsigned kernel with a message like please load the kernel..
I was only able to boot with the official 5.4.0 kernel but as you may already know this is useless in Yoga Slim 7 especially if you need HDMI.
Disabling Secure Boot in DMCN34WW didn't make any difference. I cannot figure out why 5.9 self-signed kernel fails with DMCN34WW and what was this loading ramdisk message about.
So my attempt to upgrade the BIOS failed and I had to enable version downgrade in the bios and then revert to DMCN32WW.

If anyone has a solution to install a 5.9+ kernel with DMCN34WW please post it.

Hi, I have upgraded my BIOS to version DMCN34WW and yes I can't boot the system at first. However after recreating the acpi override everything works fine.

I just successfully updated the kernel to 5.10.1 on ubuntu 20.04.1 with DMCN34WW.

Also suspending by closing and reactivate by opening the lid seems to work thus far. Suspending via the gui did not seem to work properly, but i haven't properly "tested" this

@soupli did you "Modify the system to advertise S3 support" or is this bug finally fixed with the newest bios and a 5.10.1 kernel?

[soupli]

I did no modifications whatsoever so it seems that the bug is finally "fixed". I still do experience an issue with suspending the machine via gui though.. so I am still somewhat preserved. And of course this is not a guarantee that it will work for your machine Op vr 18 dec. 2020 22:06 schreef rradar <notifications@github.com>:

I have also installed 5.10.1 and then reinstalled BIOS DMCN34WW on ubuntu 20.04.1.
I can boot the OS if I edit GRUB upon boot and remove the /boot/acpi_s3_override

I have verified that suspend still does not work for me (without the S3 patch).

Note: 11.04.04 is using lid, 11.06.33 is using the UI menu button, so it failed in both cases for me.

I am now in the process of re-creating the S3 override.

But the iasl -e *.dat -d dsdt.dat has failed too.

Same issue with both 20200717 & 20201217 acpica versions that I tried.

[ko-christ]

I have removed the acpi_s3_override S3 settings as well as the mem_sleep_default=deep from grub permanently and applied the following settings in /etc/systemd/logind.conf.

HandleSuspendKey=suspend
HandleLidSwitch=suspend
HandleLidSwitchExternalPower=suspend
HandleLidSwitchDocked=suspend\

Now everything seems to be working in 5.10.1 with DMCN34WW including suspend. I will put an update if I notice anything else.

Hm interesting, can you check the battery drop after a few hour?

I too find that the battery level has drastically dropped when the machine is suspended / paused for a time period of 7-8 hours or so. Charged it 100%, closed the lid (machine is paused), opened it ~8h later and got 33% left.
