<pre>Initially I reported <a class="bz_bug_link
bz_status_NEW "
title="NEW - GPU hang and system crash with Dota 2 using Vulkan"
href="show_bug.cgi?id=107941">https://bugs.freedesktop.org/show_bug.cgi?id=107941</a> but
I'm reporting the system crash here to make it separated.
The attached file at <a href="https://bugs.freedesktop.org/attachment.cgi?id=141570">https://bugs.freedesktop.org/attachment.cgi?id=141570</a> has
the relevant files from the GPU hang that triggered the crash but,
unfortunately, has no data from the crash itself.
With kernel versions at least 4.18 (happens with -rc too), after a GPU hang
happens the system crashes. Apparently there is no way to recover and I have to
keep the power button pressed to poweroff the computer.
4.17.19 is OK, while a GPU hang may happen, the system do not crash after that,
allowing me to use the computer normally after the hang.
I'll try to set netconsole to see if I can get any useful information from the
crashed system with this new drm-tip, but in my previous attempts there was no
output in the receiving machine.
Processor: Intel Core i3-6100U;
Video: Intel HD Graphics 520;
Architecture: amd64;
Mesa: 18.3.0-devel (git-914bd3014f);
Kernel version: drm-tip (feeccde66999c5e87be3550f2159e5d7eeb61c67)
Distribution: Xubuntu 18.04.1 amd64.
Notes:
I'm sorry for reporting so many bugs at once, it's the first time I'm using
Vulkan seriously on my computer and could keep the applications open for enough
time to detect problems.
There is a multitude of regressions affecting my computer when using kernel
versions at least 4.18 (this is the one related to i915), so I have to use 4.17
for now.</pre>
