[Issue]: set amdgpu precise-memory on crashes the system
Problem Description
Running ROCgdb and setting amdgpu precise-memory to on before running the debugger freezes the system for maybe ~30s before I get forcefully black-screened + logged out.
Not setting amdgpu precise-memory show no issues.
The freeze + "crash" issue only happens on non-trivial application: it seems to require at least some degree of computational complexity to crash. Very lightweight application do freeze the system for a few seconds with precise-memory set to on but this does not lead to a crash.
Reproducible with examples of HIPRT SDK.
Operating System
Ubuntu 22.04
CPU
Inte i5 13600KF
GPU
AMD Radeon RX 7900 XTX
ROCm Version
ROCm 6.2.0
ROCm Component
ROCgdb
Steps to Reproduce
Build the examples of the HIPRT SDK.
Debug example 08_ambient_occlusion with rocgdb:
rocgdb tutorials/bin/Debug/08_ambient_occlusion64D
set amdgpu precise-memory on
r
The same steps with example 05_global_stack freezes for some time but does not crash.
