Hi,

I'm using Debian stable (with kernel from backport).
I face a GPU crash and syslog message was inviting me to file a bug.

kernel 4.14.13 (from debian)

<span class="quote">> uname -a</span >
Linux lemon 4.14.0-0.bpo.3-amd64 #1 SMP Debian 4.14.13-1~bpo9+1 (2018-01-14)
x86_64 GNU/Linux

hardware : gigabyte ga-z270x-ud5 + intel i5-7600 (kaby lake + 4k monitor
bdm3275

debian is up to date

I have no idea of the cause, because crash happens during screensaver.
I cannot reproduce : don't know how to crash (looks random and rare - first
time in the week)
I already filed bug about crash during screensaver.

Regards,
Serge
