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:

paź 24 13:43:31 Langley kernel: [drm] Initialized nouveau 1.3.1 20120801 for 0000:01:00.0 on minor 0
paź 24 21:42:32 Langley kernel: nouveau 0000:01:00.0: fifo: write fault at 0000048000 engine 07 [PFIFO] client 07 [BAR_READ] reason 02 [PAGE_NOT_PRESENT] on channel 2 [003fc13000 Xorg[538]]
paź 24 21:42:32 Langley kernel: nouveau 0000:01:00.0: fifo: fifo engine fault on channel 2, recovering...
(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.

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.
