dmesg output
When using amdgpu.vm_update_mode=3 the following error appears after some time (ranging from a few minutes to a few hours):
BUG: KASAN: use-after-free in amdgpu_vm_update_directories
I attached the relevant dmesg part.
Notes:
- happens on Navi10 and gfx9 (probably also on other cards but I didn't try)
- reproduced on 865b4ca43816e113996c3be571d4998b6daf5f1 and 20d6b9c3b7f40ec427af912d140f2be0de098d2d
