[Toshiba Satellite C55t-A] Laptop unable to wake up after being suspended

[Rafael Santos]

Laptop was unable to wake up after being suspended by lid's closing, resulting in a blank black screen, while LEDs on the laptop showed that it had woken up. This bug happened using kernel 5.4.0-56.62, and it was "solved" by changing the kernel used to version 5.4.0-54.60, in which the default behavior of suspension when lid was closed and lock/login screen after lid being lifted up ocurred as it always was.

Can you please reproduce the issue and attach `journactl -b -1 -k` from next boot?

[Rafael Santos (rafa1822)]

Hey, I reproduced the same issue on both 5.0.4.56#62 and 5.0.4.58#64 and then created a file from 'journalctl -b -1 -k' output on the working 5.0.4.54#60 kernel version. I'll attach both of them on subsequent comments, hope you guys can solve it. Thanks for your time!

[Kai-Heng Feng (kaihengfeng)]

Please test latest mainline kernel:
https://kernel.ubuntu.com/~kernel-ppa/mainline/v5.11-rc2/amd64/

[Kleber Sacilotto de Souza (kleber-souza)]

Hello Rafael or anyone else affected,

We have released a new Focal linux kernel (version 5.4.0-59.65) which contains several bug fixes. Could you please update to this kernel and report whether it fixes the issue?

Thank you.

[Rafael Santos (rafa1822)]

Hello Kleber. I've booted with this new Focal Linux kernel (version 5.4.0-59.65) and the bug still, unfortunately, happens. So I'll have to keep using kernel version 5.4.0-54.60 until this issue gets fixed. Anyways, thanks for the update!

[Kleber Sacilotto de Souza (kleber-souza)]

Hello Rafael, thank you for the tests.

We have a test kernel with some fixes that we would appreciate if someone could test it. They can be found at: https://kernel.ubuntu.com/~vilhelm/linux-5.4.0-59.65+lp1909005/amd64/

You would need to install at least:
linux-image-unsigned-5.4.0-59-generic_5.4.0-59.65+lp1909005_amd64.deb
linux-modules-5.4.0-59-generic_5.4.0-59.65+lp1909005_amd64.deb
linux-modules-extra-5.4.0-59-generic_5.4.0-59.65+lp1909005_amd64.deb

Thank you!
