[GL702ZC] Kernel Panic when waking up after screen went blank.

[lss41771]

I'm running latest Manjaro and this problem existed since day one. At first I could not find out exactly why, but eventually after looking at journalctl I was able to find traces of kernel oops panics.

I'm able to easily reproduce it by doing the following:
1. Lock the screen, let it keep blank for a while (for at least 3 minutes).
2. Try to wake the screen up by moving the mouse.

The screen would not wake up and the computer appeared crashed. It's 100% reproducible and could be done on a fresh boot. I don't think the modules are related as it happened after fresh installs, before I eventually install the software I needed.

This is the log about one of the times that it happened. Apparently the culprit appears to be dce110_vblank_set+0x4f/0xb0 [amdgpu] with the topmost function in the call trace being amdgpu_dm_set_crtc_irq_state+0x31/0x60 [amdgpu].

I'm doing this on 4.15 kernel, but I recall the same problem occurred on 4.14 as well. It does not appear to be related to the DC, either.

When I was trying to debug and reproduce the problem I found additional error lines talking about NULL, too.
Apparently I found something different, which seems to be related and could be found before the actual kernel panic.

Are any other Linux users experiencing such problems with this laptop? At first I though it might be the distro so I posted about it on the Manjaro forums. I once thought about using a custom kernel as I did not know what the cause was back then, but I didn't have time, and it's not as convenient as in actual Arch Linux to do so. With the new discoveries, I believe the distro had nothing to do with this. As I could not find similar bugs reported elsewhere else so I think it might be both driver and device related.

For the time being, I could only mitigate it by disabling whatever that could cause the screen go blank in the Power Management options, and avoid locking the screen if possible (as it can also blank the screen). As I also use the laptop for work, I often risk losing work progress because of this...

EDIT 2: Apparently this is a kernel issue and this device is not the only one affected. I've filed a bug report here, and at present, patches were made available which fixed the crashing issue as far as I have tested.
