Vulkan Crashes my Entire Machine

[hntd187]

Normally I start up with "-phased_window_create -high -threads 12 -gl" but vulkan crashes my machine no matter what. Even running it with just "-vulkan" alone. The title screen will begin to show up, like the first half a second of it and then just freeze. Sound continues to play on the computer, but I am not able to do anything input wise. I am not even able to get a dump from the error or see what is going on around my machine as my machine completely locks up and requires a restart. I can't even get to an alternate tty via control+alt+F2 I've attached my glxinfo and my vulkaninfo maybe that sheds some light on it.

You have a very high end system that should be fine to run it obviously, it's hard to say based on the report what might be going on. Some suggestions: could you run with -con_logfile and post game/dota/console.log, there may be something useful there. Usually when you get a hang like that you might still be able to ssh in and kill the process. Also, can you try running with -threads 0 and see if it makes any difference?

[hntd187]

@danginsburg Do you mean SSH in from another machine? I can't get another tty, no keyboard input seems to be working when this occurs.

Also could it be with the vulkan api version? I have vulkan dev libs on my machine inside my LD_LIBRARY_PATH, and those are 1.0.33, does that matter?

I'll try the other options a bit later to see if I can get something. Also, I suppose while I'm asking questions, does Dota2 support Gsync or SLI on linux at this time?

If you are running it directly from Steam then it should be using the Vulkan loader inside the steam-runtime and not the one on your system.

No, not yet.

Okay so @danginsburg running this with the options you specified above, the game still locks up. I am not able to SSH from another machine, the connection just times out. The console log you specified from the run generated a 1.7gb file before I killed the machine. That's some pretty nice disk IO right there.

The nice thing about the file is that regardless of how large the file is it's basically the same file for literally a couple million lines. Attempting to purge m_fencedResourceList.Count() = 6, m_pendingFencedResourceQueue.Count() = 0, nCurrentCmdBuffersAvailable = 0, nAllocatedCommandBuffers = 1500

Here is the first 1000 lines of the log file, after that it's just this line forever.

Hello @hntd187, the log is saying you are using -phased_window_create with -vulkan. These two launch options have been reported incompatible with a log that ends with almost the same recurring line at https://github.com/ValveSoftware/Dota-2/issues/962#issuecomment-267395864. Please retest without -phased_window_create

[hntd187]

@kisak-valve Removing -phased_window_create does not change anything with the output.

loggylog.txt

This also generated a 1.3gb log file before I killed it.

[danginsburg]

The log file is indicating a GPU hang which has stalled progress on the renderthread. The main thread gets 2 frames ahead (max) and then starts to purge resources, but the fences never retire because the GPU is hung.

[hntd187]

Okay so @danginsburg What can I do now to investigate further or resolve?

[lovesmall]

• Dota2 (all other 3D games are fine) crashed my system, freeze with sounds in background. I did checked Vulkan for windows in the steam.
• I thought it's a power issue as windows event showed power-kernel error.
• I just brought a new PC cost 2k last weekend.
• I saw this post today =,=

[hntd187]

@lovesmall This isn't about windows, this is about Linux, so it probably doens't apply to you.

[lovesmall]

@hntd187 My Dota2 would crash like every game before I uncheck the Vulkan. After I unchecked it, it's good for 3 consecutive games so far. Maybe it's a cross platform issue ? I'll keep monitoring.

[kisak-valve]

Hello @lovesmall, please follow the steps earlier in the issue report to collect a console log so we can see how closely the symptoms match.

[Ace5040]

same issue here but whole operating system become unresponsible right after alt-tab. if not alt-tabing can play as long as I want

OS: Archlinux Desktop env.: lxqt nvidia 1060 3gb msi - driver 387.22

log: console.log

with -gl all works just fine

[lovesmall]

Hi, I think issue for me is my video card. 1070 seems unstable after 1 year of use. It's ok after I replaced it.

[hntd187]

Although I have no proof of this I figured that the issue had something to do with my SLI setup at the time. I've since moved to a 1080Ti and that plays vulkan dota2 totally fine, which is the closest thing I have to any proof of my theory. But I also understand that linux dota2 doesn't use SLI, so that probably isn't it either.

[Ace5040]

I have found combination of resolution/mode wich works. I mean alt-tab doesn't lead to crash.

works fine: 1600x900 - window/borderless window all others crashes on alt-tab: 1920x1280 - fullscreen 1920x1280 - window/borderless window 1600x900 - fullscreen

After a system update (and upgrade to nvidia's 390.25) I am also randomly getting these complete freezes when restoring dota2 -vulkan from being minimized. However I am able to ssh in remotely and 'killall dota2 -9' to recover the desktop. console.log

[evantandersen]

Also suffering from this issue. Ubuntu 16.04 with nvidia driver 384.111 on a GTX 970.

Disabling vulkan fixes the issue.

[Squall-Leonhart]

These system are crashing because 16.04 doesn't include the HT Flaw microcode fix and the users have not updated the bios to include the microcode either.
