Hi
I’ve booted HiFive Unleashed with Debian OS, and now I’m trying to run stress-ng to test the CPU performance, but the kernel will crash when I run stress-ng. I’m not sure if it’s caused by CPU itself or the kernel, the software(stress-ng). Can anyone give me some suggestions to solve it?
PS: I tried “swapoff -a”, but it’s helpless.
