            Bug ID: 97840
           Summary: [regression] [tonga] Freeze since new memory manager
                    enabled
           Product: DRI
           Version: XOrg git
          Hardware: Other
                OS: All
            Status: NEW
          Severity: normal
          Priority: medium
         Component: DRM/AMDgpu
          Assignee: dri-devel@lists.freedesktop.org
          Reporter: mike@fireburn.co.uk

Created attachment 126589
  --> https://bugs.freedesktop.org/attachment.cgi?id=126589&action=edit
Glxinfo

Regression since:

drm/amdgpu: add a custom GTT memory manager v2
5b03b7a0f28d68ca4015b1b5ad27cb70641b7ebd

Nothing shows up in the dmesg, 3D games don't start, glxgears kinda starts and
the window just shows white

The system then becomes partially unresponsive and slowly becomes totally
unresponsive

I managed to capture the freeze in glxinfo - if that helps

Reverting 5b03b7a0f28d68ca4015b1b5ad27cb70641b7ebd fixes this for me, I should
also make clear this is a Skylake/Tonga laptop

Mike, have you tested https://patchwork.freedesktop.org/patch/110851/ and
possibly the more recent patches on
https://patchwork.freedesktop.org/project/amd-xorg-ddx/patches/?submitter=11066
?

Part #1 of the fix.

First part of the fix. Might help with the white window, but there are clearly
more bugs to fix.

Still working on this.
