Vega issue

[tildearrow]

Update: it crashes on AMDGPU-PRO as well, although very rarely (~2 times per month). Is my card defective?

Playing with kernel config you can try to make it stable. Try also https://cgit.freedesktop.org/~agd5f/...d-staging-4.12 kernel. Phoronix did not have such problems, maybe you should try with Debian testing , a custom kernel and Padoka ppa.

I'll check if this reproduces using a different distro later, I think.

You are using really old kernel, no wonder you vega does not work. Forget your rt patches and use agd5f wip kernels. Make a non debug 1000Hz timer kernel, there is enough real time. Check that you have enabled: Reroute Broken IRQ, Virtualization KVM and 1000Hz CPU timer, I also disabled Swap, Kernel Debug, CPU Freq scaling , Cpu handling in Acpi, Used Bios to control CPU and devices.

I doubt that's going to help. I have most of these things set.

Also, did you read I tested the amd-staging-drm-next kernel?

[tildearrow]

Not really. I just tried with amd-staging-drm-next and hung again.

(although it took much longer to hang)

[agd5f]

Does removing the RT patches help?
You can also try these branches:

https://cgit.freedesktop.org/~agd5f/linux/?h=amd-staging-drm-next

or

https://cgit.freedesktop.org/~agd5f/linux/log/?h=amd-staging-4.12

So I've got a Vega FE some time ago, and I'm having a major trouble with the open driver.

The issue is that after ~3-30 minutes of uptime, under X, the card hangs and the tach turns fully on. And I'm unable to recover a console (not even via SysRq).

I'm still able to use the hwmon, though.

amdgpu_gpu_reset only prints "[drm] No hardware hang detected. Did some blocks stall?" in the dmesg.

Memory usage has been fine, so it is not a memory leak.

The card works perfectly under AMDGPU-PRO.

I'm using the kernel driver from AMDGPU-PRO, with the Mesa userspace driver, because I don't want to quit using the awesome RT patches.

Oh, and the system's specs:

- Motherboard: MSI Z170A GAMING PRO
- Processor: Intel® Core™ i7-6700K (stock freqs)
- Distro: Arch Linux
- Kernel version: 4.9.20-4-rt16-rt-bfq
- LLVM/Clang version: 5.0 RC2
- Mesa version: 17.2-rc4

I'll try to provide more information if needed. Thanks for almost any help.

Oh, one more thing: I don't want to use Debian testing with XFCE and Ubuntu packages.
