Hi folks,

my best guess is that this is an use after free.
Going to double check the code, but can you reproduce this issue reliable?

Ah, this asic is a bit old and still use radeon driver. So we didn't reproduce it on amdgpu driver. I don't have such the old asic in my hand. May we know whether this issue can be duplicated after SI which is used amdgpu module (not sure whether you have recent APU or GPU)?

Ah! Thanks Ray for pointing this out. I have SI based hardware here.
Going to try this in a few minutes.

The latest I have (I think it is the latest) is:

Yes! Renoir is late enough for amdgpu kernel module. :-) Please let us know if you still encounter the issue.

Ah, this asic is a bit old and still use radeon driver. So we didn't reproduce it on amdgpu driver. I don't have such the old asic in my hand. May we know whether this issue can be duplicated after SI which is used amdgpu module (not sure whether you have recent APU or GPU)?
The latest I have (I think it is the latest) is:
[ 1.826102] [drm] initializing kernel modesetting (RENOIR 0x1002:0x1636 0x17AA:0x5099 0xD1).
and so far that hasn't triggered it. Which makes sense because that thing uses amdgpu:
[ 1.810260] [drm] amdgpu kernel modesetting enabled.
Yes! Renoir is late enough for amdgpu kernel module. :-) Please let us know if you still encounter the issue.
Thanks for the hints guys. You need a rather specific configuration, but I can reproduce this now.
Let's see what the problem is here.
FWIW I'm seeing it here on my workstation too.
Should be fixed with this patch set I think: https://patchwork.freedesktop.org/series/85515/
