Hi all,
I am trying to set a “ERR0PFGCDNR” this is an countdown register which, when activated, will countdown to zero and then produce a error. This is not activated and I can currently read this value which is 0. But when I try to enter a value into this register, using a kernel module, I get the error bellow:
s▒▒Unhandled Exception in EL3.
x30▒▒ kernel.
[ 489.985018] rcu: INFO: rcu_preempt detected stalls on CPUs/tasks:

Can you reproduce this error and try and find a fix for this?
