Hello, a Debian user reported an issue while using the amdgpu user. The full details are available at https://bugs.debian.org/1139599. The relvant (I hope) parts are also in this mail, but you can find more logs there if you want to take a look.

Also it would be great to know, how reliably you can reproduce the issue, in case we have to resort to bisecting or testing a fix. Is this a regression, i.e. did the same workflow work fine before, with an older kernel version? If so, which one? > Jun 09 23:00:08 frame kernel: slab kmalloc-96 start ffff8ca660fea420 pointer > offset 64 size 96 > Jun 09 23:00:08 frame kernel: list_del corruption. next->prev should be > ffff8ca661e9ed60, but was ffff8ca623eb9180.

Does this ring a bell for you anyhow? There are a few amdgpu changes in 7.0.11 (since 7.0.10 which is the kernel that showed the issue), but they don't look (to me that is) as if they would resolve the problem. Best regards Uwe
