Firefox crashed complete system

For two days now, opening firefox or rather beginning to open a website inside firefox (after it has been started), will crash my complete system.
There is no reaction I can get afterwards at all, the only thing left is hard reset.

When I looked at the logs using journalctl or dmesg there was no trace of it, no kernel panig message or anything of the sorts.

This has started after upgrading gtk to version 3.22, so I suspect this might be related.
Has anyone experienced simular isues.

Is there something left to look at regarding log files or some other means of diagnosing the problem?

Re: Firefox crashed complete system

Probably just a frozen compositor.
Can you Ctrl+Alt+F1 when this happens? Or ssh into the machine?
Which Desktop environment do you use and does this also happen with eg. fluxbox or icewm?

You could try downgrading gtk3 to 3.22.1-1 (without the patch +8+ge11df6c-2).
Does it solve the problem?

Indeed I just installed xcompmgr the other day. However after removing it the random crashed occured again.

Ctrl+Alt+F1 (or F2-F7) does not work. There are no network services on the machine
I'm using the awesome wm and there are not other userspace processes running besides the xserver, dbus and the basic systemd stuff.

What phases me the most is the fact that a userspace process can do that, which to my knowledge, is only the case if the problem goes deeper.

I have not yet tried downgrading gtk, will do so soon if I can't find the issue otherwise

Re: Firefox crashed complete system

You don't need any network service (while good to have on debugging) to ping the machine. If it's alive (and there's no überambitious firewall) it will echo.

That's however no good sign and smells a lot like a stalled kernel. The culprit will in this case be the gpu driver (kernel module) which reacts badly to some - legal or not - GL call from firefox/gtk.

That will be it. I'm using the new amdgpu driver, which didn't make any problems up till now, but it is probably the culprit. I suspect gtk 3.22 did trigger some error the driver couldn't handle.
Will try to downgrade gtk and see if the error occurs again.
