AMD uProf fails on first attempt with following error:
"The driver failed to start profiling. (error code 0x80070021) Some other process or service has locked the profiling hardware (IOCTL_START_PROFILER)"
I've checked per system informer and process explorer and got two processes accessing \Device\AmdPowerProfiler0:
After dismissing the message, uprof will begin to "collect" data on any new attempt to profile, but will not actually collect anything. Error:
"The raw file has no data!"
