            Bug ID: 109973
           Summary: System hangs/freeze/hiccups
           Product: DRI
           Version: XOrg git
          Hardware: x86-64 (AMD64)
                OS: FreeBSD
            Status: NEW
          Severity: critical
          Priority: medium
         Component: DRM/AMDgpu
          Assignee: dri-devel at lists.freedesktop.org
          Reporter: walterkrupp01 at gmail.com

Hi all,

My system is:
CPU: AMD Ryzen2 2700x
MB: Asus x470-F
Memory: Corsair 32GB PC3200mhz
GPU: Asus Rog Strix Vega 64
Monitor: Asus MG279Q ( 2560x1440, 144hz ) (connected at display port 0) +
(FreeSync is ON from Monitor Settings) (also tried OFF)
Disk: Corsair Nvme 1920gb
OS: Freebsd 12 p3

Problem Description: Sudden FPS dropouts and sometimes full system freeze/lock
(requires hard reset), + and time to time 15/30ms freezes (doesnt require hard
reboot but happens exactly the same time with sudden fps dropouts)

can be problem caused by dynamic power management of gpu/amdgpu ? ( i did
amdgpu.dpm=0 at /boot/loader.conf but doesnt seem to effect.. )

Note: all the hardware above has been tested at another pc, they work
flawlessly at arch linux (no freezes no hiccups no sudden fps dropouts) (so
hardware are fine)

clinfo reports;
Number of platforms 0

.. so I'm confused about what works and not or partially works in my system..
(opengl,opencl,vulkan,rocm?,etc..) (+which packages/ports are missing and need
to be installed..)

Attached files are: (due attachment limit per post were 5 files max, i posted
the rest of the files with my other posts in this topic)
1> uname -a
2> kldstat
3> xrandr
4> /boot/loader.conf
5> /etc/rc.conf
6> dmesg
7> /var/log/messages
8> xorg.conf
9> /var/log/xorg.log.0
10> /var/log/Xorg.log.0 (when full system freeze occurs)=> "[mi] EQ
overflowing." + "[mi] This may be caused by a misbehaving driver monopolizing
the server's resources."
11> pkg info (installed packages) (comparison with arch wiki amdgpu + xorg
amdgpu + https://wiki.freebsd.org/Graphics)
12/13/14/15> glxinfo + glxgears + vulkaninfo + vdpauinfo
16> pciconf -lvbce
17> devinfo -vr
18> sysctl hw.model
---> total 18 files.

Since I cant attach all the files above to this bug report, i submit the
link/url that I have attached them to..
