Same problem here only on Ubuntu 14.04 x86_64 bought the game yesterday went to play it today and it would crash on start simmiler crash log. waitting for apt to install new kernal will try game again after update.

Looks like it related to a kernel module. Maybe the nvidia driver, but I don't know why. Other games works on 3.17.7.

I got the same issue with the game, was working well since I updated to Fedora 21, but with latest system update, the game crash on startup. Im also running 3.17.7-300.fc21.x86_64

Try to start your system with the 3.17.6 kernel(i use grub-customizer, it's easy).

bump

Same thing on Arch x64, kernel 3.18.2.

Can you indicate if you are using steam-runtime or not ?
The crash at eON_FileSystem::setUniqueAppId() is very odd, because all this does is assign two std::string values!

Here is some relevant log when I run steam in a terminal.

Running Steam on fedora 21 64-bit

Like I said, the game won't launch when I use a kernel newer than 3.17.6.

Also, there is occasionally a bug report too when the game close.

Not a big deal for now. I can still play with 3.17.6.

Yes, Steam runtime is on, but conflicting libraries are deleted (libgcc_s.so*, libstdc++.so*, libxcb.so*). Without deleting these files, Steam won't work. Crash log is sent in through the launcher and also posted on github.

Sadly can't start the game either. A tad dissapointing as the Linux version was the tipping point for purchasing the game...

Hum, Steam works for me without deleting any lib. You mean that you deleted those lib from the Steam runtime?

Yes. Fedora has outdated libs compared to Arch, and the conflicts happen if you're using the Radeon driver. So you may not have SR conflicts or may be using proprietary drivers.

Same here: Arch Linux x64:(. Ok, at least you guys are onto something. Was a bit annoyed. Today, I bought an nvidia gtx 970 for ..eg Witcher 2 since the gtx 285 doesn't suffice for the witcher 2 in Linux. Old one had lags as fu** .. new one ..crash. And this was exactly in between 3.17.<something> and 3.18.2 which I upgraded to yesterday or so. Unfortunately I cannot downgrade to 3.17.6, because I had to use the 340xx version with the gtx 285, since nvidia dropped support for everything below series 4xx or so in the 340 line.
So, I was using the 340xx line for the last few months -> no 343 version for kernel 3.17.6 in my pacman cache.

My solution is just to install the proprietary driver while I run the good kernel. So it build and install the driver kernel module. I boot in runlevel 3 to install it and then reboot into 5.
