Hi there,
I've installed the ROCM runtime on my (Debian testing) machine (upstream kernel 5.3.14-1, dual-socket Haswell Xeon) following the instructions. When I run clinfo, I get a segfault. Adding "HSAKMT_DEBUG_LEVEL=7" sheds a bit more light, but not much:
$ HSAKMT_DEBUG_LEVEL=7 /opt/rocm-3.3.0/opencl/bin/x86_64/clinfo

The backtrace from gdb is not very informative, other than placing the crash somewhere inside the OpenCL runtime:
Thread 1 "clinfo" received signal SIGSEGV, Segmentation fault.

What can I do to troubleshoot this?
