Hi, This is slightly different, there is no panic message here. However, this instruction is unimplemented, but is required by the application for its execution, causing it to abort. As in your link, Gabe mentions that we need to tell the compiler not to use this instruction. I was unsure how to achieve the same, I tried passing the -msse flag to gcc during compilation, but the movntdq instruction still seems to be getting generated.
