Description Marcin Mielniczuk 2016-04-01 15:57:54 UTC
uname -a:
 Linux arch 4.1.20-1-lts #1 SMP Fri Mar 18 17:26:44 CET 2016 x86_64 GNU/Linux

I'm using Cinnamon. When launching Netbeans, I experience a hang. After that the GPU acceleration gets disabled.

I'm able to reproduce this in another usecase: opening a file in Eclipse. This seems to affect Java applications in some special way

This is my whole setup (including HW setup, which was missing)

Comment 9 Alexey Kharlamov 2016-05-25 18:36:49 UTC
Able to reproduce it (not saved the card dump yet -- system hangs)

Reproducible: 50/50 when I launch some intensive load (like package compilation)

I've tried to use xorg modesetting driver, but it seems to cause gpu hang on xorg startup.

Comment 16 Alexey Kharlamov 2016-05-27 16:10:10 UTC
I have found out that hangs disappear when I disable VT-d in BIOS.
Comment 17 Jari Tahvanainen 2017-03-09 12:17:36 UTC
Marcin, Alexey - I'm sorry about this delay on getting back to you. Is this problem still valid? Have you tried the newest kernel, preferable generated from drm-tip? If yes then please provide new dmesg and card0/error data.
