A part of journalctl, describing process of crash
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 read:

(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.
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:
- Close the laptop so it goes to sleep
- 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.
