Hi Jatin, Sure, here is the requested info for the rocm version I am using. `HIP version: 5.4.22802-aaa1e3d8 AMD clang version 15.0.0 (https://github.com/RadeonOpenCompute/llvm-project roc-5.4.1 22465 d6f0fe8b22e3d8ce0f2cbd657ea14b16043018a5) Target: x86_64-unknown-linux-gnu Thread model:...

Sure here are the temp files for when compilation with -O0 produces an error. `hipcc -O0 -save-temps mat_mult_bugreport.cpp -o a.out` The files for buggy compilation are here [mat_mult_bugreport-hip-amdgcn-amd-amdhsa-gfx1035.bc.txt](https://github.com/ROCm-Developer-Tools/HIP/files/11007008/mat_mult_bugreport-hip-amdgcn-amd-amdhsa-gfx1035.bc.txt) [mat_mult_bugreport-hip-amdgcn-amd-amdhsa-gfx1035.s.txt](https://github.com/ROCm-Developer-Tools/HIP/files/11007010/mat_mult_bugreport-hip-amdgcn-amd-amdhsa-gfx1035.s.txt)

Here are the temp files for normal compilation where the code works fine. `hipcc -save-temps mat_mult_bugreport.cpp -o a.out` [mat_mult_bugreport-hip-amdgcn-amd-amdhsa-gfx1035.bc.txt](https://github.com/ROCm-Developer-Tools/HIP/files/11007024/mat_mult_bugreport-hip-amdgcn-amd-amdhsa-gfx1035.bc.txt) [mat_mult_bugreport-hip-amdgcn-amd-amdhsa-gfx1035.s.txt](https://github.com/ROCm-Developer-Tools/HIP/files/11007025/mat_mult_bugreport-hip-amdgcn-amd-amdhsa-gfx1035.s.txt)

Hi folks, Just an update to this. I am still seeing the problem with ROCM 5.4.3. I now have access to an officially supported GFX906 architecture and I am seeing...

Hi! On GFX1035 I have given up trying to use the **amdgpu-dkms** driver because it messes around with my laptop display. This behaviour **did not occur with ROCM 5.7**. On...

Sorry @sohaibnd the issue still remains on gfx906. ```bash hipconfig HIP version: 6.2.41133-dd7f95766 ==hipconfig HIP_PATH :/opt/rocm-6.2.0 ROCM_PATH :/opt/rocm-6.2.0 HIP_COMPILER :clang HIP_PLATFORM :amd HIP_RUNTIME :rocclr CPP_CONFIG : -D__HIP_PLATFORM_HCC__= -D__HIP_PLATFORM_AMD__= -I/opt/rocm-6.2.0/include -I/include...

Hey @sohaibnd, on gfx1035 (without amdgpu-dkms because it somehow messes with my screen?) I **don't** see the error, ```bash hipcc -O0 mat_mult_bugreport.cpp; ./a.out Maximum error (infinity norm) is: 5.72205e-06 ```...
