System Information
Operating system: Arch Linux 6.6.3-zen1-1-zen
Graphics card: AMD RX 6700 XT
Blender Version
Broken: 4.0, 3.6
Worked: 3.6Short description of error
Blender hangs completely when trying to select Cycles rendering with GPU or selecting HIP in Preferences > System.
Exact steps for others to reproduce the error
Alternatively:
Launching with --debug-all did not clarify the issue:
Steam version does not work as well.
Hi, thanks for the report. Could it be because render kernels were loading? Does it returns to normal state after waiting for some time?
Launch blender with --debug-gpu or --debug-cycles , it may capture some useful info about the freeze
Do you use blender builds available on website?: https://builder.blender.org/download/daily/
Hello, I am also experiencing this issue, even in blender 3.6.6. See logs below.
System Information:
Arch Linux 6.6.3-zen1-1-zen
GPU: AMD ATI Radeon RX 6600
Exact steps for others to reproduce the error
Logs
(with blender-4.1.0-alpha+main.153f14be2b67-linux.x86_64-release)
(with Blender 4.0.1)
(with blender 3.6.6)
In all cases, blender hangs for sevral minutes with no additional log messages.
I notice both of us are using the zen kernel. I will try using the regular linux kernel and report back.
Also attached: output of glxinfo command, in case it proves usefull.
Using the regular kernel exhibits the same behaviour. I also had instances where selecting the HIP options causes the whole system to freeze. This was noticed using both the regular linux kernel and the zen kernel. This sounds similar to blender/blender#100353.
System Information
Operating system: Arch Linux 6.5.6-arch1-1
GPU: AMD RX 5700
Hi, I had the same issue, and it looks like it's a bug in the amdgpu driver: https://gitlab.freedesktop.org/drm/amd/-/issues/2991.
Downgrading from linux 6.6.3 to 6.5.6 fixed it for me, so I hope it does for you too!
Same issue here.
I'm on Fedora - 6.6.3-200.fc39.x86_64.
GPU: AMD RX 6600.
Blender version: 4.0.1
Havn't tried downgrading to an older kernel as you suggested Maks-Rawski, but since the problem has just started recently (and it has worked previously) that sounds like a good thing to try.
Downgrading to 6.5.6 did fix it for me as well.
Thanks. I'll confirm for now until it gets fixed from kernel/driver side.
Guess switching proprietary driver might also avoid this problem: https://gitlab.archlinux.org/archlinux/packaging/packages/blender/-/issues/2#note_141974
Can confirm, installing
amdgpu-pro-oglp
(AUR) and launching withprogl blender
fixes the issue.Thanks Pratik for advice.
Since the issue is not with Blender itself, but with Linux kernel and/or FOSS driver, I guess I will close the issue.
