Hi burak,

your stack is different. See dce110_opp_program_regamma_pwl vs
dce110_stream_encoder_update_hdmi_info_packets on the stack.

Can you open a new ticket?

Thanks,
Harry

Hi, sorry to bother for closed issue but I am having exact same error on every
boot, I build kernel from master head of linus repo, fedora with Fury X gpu. Is
this related with my driver? i have xorg-x11-drv-amdgpu.x86_64

No worries. Don't hesitate to open a new ticket if your warning/error log seems
to indicate amdgpu. I'd be happy to take a brief look.

Even if I won't have time to provide an immediate fix it will still allow me to
better understand what problems people have with our driver and where we might
need to spend more effort.

I'm sorry, I think I've been mislead by the warning so I didn't actually go
through the stack properly on my recent boot. What I'm seeing now seem to be
the same warning line, however it shows a different stack and hence most likely
a different issue. And of course I was wrong to say crash, as nothing stops
after those warnings.

The crash I'm trying to debug is something completely different(every time I
lock screen, machine hangs at least keyboard/screen etc.), I'm just trying to
filter out the other warnings/errors I see to figure out what might be related.
Sorry for the disturbance :)

I believe it was this:
8acad1a18a78 drm/amd/display: Add regamma lut write mask to SOC base

Which commit fixes this? I merged in agd5f/drm-fixes-4.17 into linus master:
Merge: 3be4aaf4e2d3 7ad35721e7d5

I still see these crashes on every startup, with the following graphics card:
01:00.0 VGA compatible controller: Advanced Micro Devices, Inc. [AMD/ATI] Tonga
XT / Amethyst XT [Radeon R9 380X / R9 M295X] (rev f1)

I couldn't try drm-next-4.17-wip because RX Vega 56 hangs immediately after
start gdm with this kernel: https://bugs.freedesktop.org/show_bug.cgi?id=105833

But I checked this issue on mainline kernel:
https://git.kernel.org/torvalds/t/linux-4.16-rc7.tar.gz and don't saw that it
happens on 4.16-rc7

Can you try the latest amd-staging-drm-next or drm-next-4.17-wip from
https://cgit.freedesktop.org/~agd5f/linux? It should be fixed now.
