Hi there. I recently came across this as well. I have a strong feeling that
this is related to amdgpu. The attached dump was taken from a machine that had
Radeon RX 560 GPU. Unfortunately, all my other crash dumps (they were
different) were lost. A few days ago I replaced that GPU with Radeon RX 6400.
No crashes since then.
