Comment 1 Harry Wentland 2018-02-28 16:08:48 UTC 
Is this on a Vega or Raven ASIC?

If so it's known and a fix should land shortly.

This is Sapphire Radeon RX VEGA 56
Comment 3 Harry Wentland 2018-03-27 17:28:38 UTC 
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.
Comment 4 mikhail.v.gavrilov 2018-03-31 13:42:20 UTC 
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
Comment 5 mikhail.v.gavrilov 2018-03-31 13:44:58 UTC 
But I see that on mainline kernel still happens another issue:
[43261.036201] amdgpu 0000:07:00.0: swiotlb buffer is full (sz: 2097152 bytes)
[43261.036205] amdgpu 0000:07:00.0: swiotlb: coherent allocation failed, size=2097152

Comment 6 Harry Wentland 2018-04-24 18:48:52 UTC 
Marking resolved as no longer an issue on recent mainline.

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

Are you seeing a crash or simply the error log described in this ticket?

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 :)

Comment 10 Harry Wentland 2018-04-26 19:44:48 UTC 
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.

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               (18.0.1-1.fc27)

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
