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

Able to reproduce it (not saved the card dump yet -- system hangs) Reproducible: 50/50 when I launch some intensive load (like package compilation)

Created attachment 124093 [details] corresponding dmesg
Created attachment 124094 [details] corresponding Xorg.log
I've tried to use xorg modesetting driver, but it seems to cause gpu hang on xorg startup.
Created attachment 124108 [details] got more verbose dmesg this time
I have found out that hangs disappear when I disable VT-d in BIOS.
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.

I can't reproduce it anymore.
