            Bug ID: 107889
           Summary: colors are wrong on one screen with Radeon RX Vega M
                    GL and Kernel 4.18
           Product: DRI
           Version: XOrg git
          Hardware: x86-64 (AMD64)
                OS: All
            Status: NEW
          Severity: normal
          Priority: medium
         Component: DRM/AMDgpu
          Assignee: dri-devel@lists.freedesktop.org

Picture with the 3 monitors. The colors at the center one are wrong

I have a 3 monitors setup on a NUC8i7HNK (with latest BIOS: 0049).

I'm currently using Kernel 4.17 + DRM patches for 4.18-rc1. Everything works
OK. However, upgrading the Kernel to 4.18.5 (kernel-4.18.5-200.fc28.x86_64)
causes that the center (and default) monitor to mangle colors. The same issue
also happens with upstream Kernel 4.18 vanilla.

I'm enclosing a picture of what's happening there.

Can you bisect?  Also please attach your dmesg output.

Bisect didn't work. There is a regression between 4.17 and 4.18-rc4 on ext4fs
that causes it fail to mount a file system:

set 11 08:16:49 coco.lan kernel: EXT4-fs (dm-13): ext4_check_descriptors: Block
bitmap for group 0 overlaps block group descriptors
set 11 08:16:49 coco.lan kernel: EXT4-fs (dm-13): group descriptors corrupted!

Forgot to mention, but the bug also happens on 4.18.0 vanilla.
So, the bug is somewhere between drm-next-2018-06-06-1, e. g.

between this changeset:

There are ways to deal with that, e.g.:

* Manually apply the fix for the ext4 regression when necessary
* Run "git bisect skip" for commits which aren't testable
* Manually find another commit which can be tested

I tried to bisect, but I was unable to find the patch with broke it. I suspect
it could be some sort of race condition, perhaps when retrieving EDID from the
3 monitors. Which buggy Kernels, the collor has a chance to be mangled during
X11 start and after DPMS screen on. Sometimes, it goes fine, sometimes, it gets
messed.

Anyway, since yesterday I'm using Kernel 4.20, with the latest linux-firmware.
It seems that the issue vanished, but I need to keep it running for a while to
be certain.
