"During the boot, when initialized devices have been listed, I have noticed that every time /dev/pmu device is fail. Please, may do someone explain to me, what do this /dev/pmu stands for the hardware inside my computer? And does it something important or not?"

CFE sets the PMU.
If there was a problem it would give you an error there.

Thanks Chris, I will bother you here more then on support tickets, as solutions go public.
SetPMU is A4 and doing well, so I ll just ignore it on Linux boot sequence.

The Linux want to activate /dev/pmu but it can because CFE has done it bevore. (On my x86_Laptop its the same Failure)
The same is why activate CPU_Core-0 fails too. Yeah an Activated Core cannot activate when its alive

Short and simple, thanks

Linux scripts should learn to say '"already activated", its not all 0 and 1 out there
