A part of journalctl, describing process of crash

Description:
When I suspend (close) my laptop and then try to wake it up, it freezes;
everything is displayed, however, inputs stop reacting and everything on screen
stops moving too. It happens only with GUIs - when I suspend it while in
terminal, it works fine (when I go back to GUI it switches and then freezes,
sadly).
According to journal, this is because of Nouveau having trouble with memory

(don't mind Polish month)

Usually, keyboard works just for a few seconds (Caps/Num Lock LEDs react),
touchpad doesn't. I don't think the whole system crashes, I believe it's still
working but is blocked by unresponsive driver.

I believe that if I wait 10 minutes or so, it actually may start working again;
however, reboot is faster in this case.

If I just let my laptop be, so it suspends while open, it wakes up perfectly.

Specs:
Distribution: Arch
Kernel: 5.3.7-arch1-1-ARCH (tested mainline 5.4.0-rc4, bug still occurs; also
occurs on other, older kernels; didn't test other distros)
Laptop: Sony Vaio, model VPCEH2D1E C1065BHW 
GPU: GeForce 410M

Steps to reproduce:
1. Close the laptop so it goes to sleep
2. Open it and press something
Since I couldn't find anyone else with this same error, I suppose you need
similar/same model, graphic card or configuration (Sony Vaio with 410M etc).

I am attaching a part of journalctl (starts at lid closing).

Also, I was instructed to report the bug here at the Arch bug list, where I
first described the bug.
