need help on llama.cpp in docker container with arm64 (raspberry pi 5)+ vulkan + amdgpu

[zphilip]

Hi
My arm64 (raspberry pi 5)+ vulkan + amdgpu (Rx 6700xt) work fine in physical machine with raspberry pi OS (6.6.y).. the problem is the docker container based on that. I create docker container to run llama.cpp : debian bookworm (arm64)+ vulkan + amdgpu (Rx 6700xt)... with map /dev/dri/ , but it failed with following output , what's the "Bus error (core dumped)" mean?
