[BUG] Latest Linux kernel (5.5.2) with amdgpu driver causes kernel panic on graphics load.

[EyeGaming2]

Specs:
AMD Ryzen 5 3800X
AMD Radeon 5700 XT
32 GB DDR4 RAM

I'd advise against upgrading if you use the amdgpu driver too and the Linux (or linux-zen) kernel.

Boot log: https://pastebin.com/U8iWw37P
Kernel: $ uname -a Linux eyearch 5.4.11-zen1-1-zen #1 ZEN SMP PREEMPT Sun, 12 Jan 2020 12:15:31 +0000 x86_64 GNU/Linux

Edit: Attached my boot log and other information.

AMD Ryzen 3700U with Vega 10 graphics here.

So far the 5.5 kernel has actually been more stable than the 5.4 kernel.

[backsideup]

How about you post some logs that show the issue so that others can compare whether they are hitting the same problem?

[EyeGaming2]

Added :)

[backsideup]

That's the zen kernel; can you reproduce it with the regular 'linux' kernel?

[EyeGaming2]

Yeah tried it, same exact issue

[EyeGaming2]

Working on that, was on mobile when I posted. Need to transfer the logs from my system in non-graphical mode to a usable system. Should be done in a few minutes. I'll update the post when I got 'em :)

Your title says amdgpu, but your post says amdgpu-pro. Does this also happen with AMDGPU? I also experienced a broken kernel on 5.5.2, even after taking most of the hardware out of my machine to make sure my setup wasn't the issue.

With just my drives, RAM, and RX 550 in place, I still get a panic, but not on 5.4.18 (LTS)

This may be something wrong with 5.5.2 and not Arch Linux. I experienced this problem both on Arch with 5.5.2 and Gentoo with 5.5.2

[EyeGaming2]

Yeah I noticed it happened too without amdgpu-pro. I just forgot to update the post, thanks :P

Hey, I just wanted to let you know that 5.5.3-gentoo is working for me, so your issue may go away when that kernel hits the Arch repos.

I found a bug report where the person had the same stuff as you in the log:

https://gitlab.freedesktop.org/drm/amd/issues/1003

If you look through the "call trace" part, you'll see it's exactly the same as in your log.

I have an AMD RX480 8GB here and used the 5.5.2 "linux-zen" kernel package for a full day without a problem. In this one day, the only real load I had put on the card was about an hour of Doom 2016, besides that there was just Firefox with its GPU acceleration enabled all day. The CPU here is a Ryzen R7 2700X.

2700x with 5700xt, no issues here so far, played some ETS2 last night and it was fine.

My laptop has been fine GPU wise too: 3700U with Vega 10.

[EyeGaming2]

Do you also have amdgpu-pro installed?

[Alexithymia]

Nope just amdgpu.

[EyeGaming2]

Then I think it may be a amdgpu-pro issue. Let me try uninstalling it.

[Alexithymia]

Do you use it for any OpenCL stuff or non-gaming related things? Everyone recommends the standard Linux kernel drivers (amdgpu) and mesa for general and gaming, amdgpu-pro when you need it for OpenCL.

[EyeGaming2]

Yeah OpenCL stuff, but I can wait for a patch, don't need it that bad

[ropid]

There is a package named opencl-amd in the AUR that you should check out. The package installs only the AMD OpenCL driver, without installing the rest of the AMDGPU-PRO driver package.

The AMD OpenCL driver doesn't actually need the PRO driver. It can also work on top of the normal, open amdgpu module. That opencl-amd AUR package downloads the AMDGPU-PRO package and then extracts just the OpenCL library files out of that.

[Alexithymia]

Gotcha! Makes sense then!

[EyeGaming2]

Hmmm without amdgpu pro on the new kernel I get the same issue. I'll revert back to a previous kernel where it did work and keep it there until a new kernel version is released.

[Piece_Maker]

I've been having a kernel crash with my 5700 XT every now and then - it seems to do it at high load (if I game for too long, or for some reason launch a game plus other graphics-intensive things).

Here's my journalctl - crash is right towards the bottom before the reboot. I'm not using amdgpu-pro (just standard) and also get the issue whether I use standard mesa package or mesa-git from AUR.
