After I created a watchpoint in Totalview in ARM64 code, and run debugger, my whole system get down and reboot. Apparently there is something wrong with either OS or hardware. Any clues?
This seems not specific to cuda-gdb, as just standard gdb will show this behavior too - enable hardware watchpoints will get whole system down and reboot.
If you insist to debug using hardware watchpoints, try binding the application to any CPU other than CPU0.
